1. A power supply apparatus that supplies electric power to an electric outboard motor for a hull through a cable, the power supply apparatus comprising: a battery pack;a battery pack mount unit to or from which the battery pack is attached or detached;a battery pack controller that manages a state of the battery pack; anda battery pack case that has a box-shape structure and houses the battery pack, the battery pack mount unit, and the battery pack controller,wherein the battery pack case includes: a case body having an opening through which the battery pack is inserted or removed,a cover member that closes the opening of the case body so as to be liquid tight, a ventilation hole penetrating through one side surface of an outer wall of the case body,a filter apparatus provided in the ventilation hole that prohibits liquid to pass therethrough but allows gas to pass therethrough,an electric power take-out section formed in the one side surface and supplying the electric power from the battery pack to the electric outboard motor through the cable,a seal material having a liquid-tight function and provided to the electric power take-out section, a carrying handle including a pair of expandable and contractible tubular shaft portions that extends in a vertical direction of the battery pack case, is attached to the one side surface from outside, and is positioned at each of a expanded position and a contracted position, and including a handle section bridged between leading ends of the shaft portions, andwheels disposed in a lower corner portion of the one side surface to assist movement using the carrying handle, andwherein a gap is provided between the battery pack case and the battery pack, and the ventilation hole is formed in each of an upper portion and a lower portion of the one side surface so as to communicate with the gap, the upper portion being located on the upper side of the one side surface in a vertical direction and the lower portion being located on the lower side of the one side surface in the vertical direction, andwherein the ventilation hole formed in each of the upper portion and the lower portion of the one side surface and the electric power take-out section formed in the one side surface are formed in an area of the one side surface defined below the handle section in the contracted position and between the pair of shaft portions. 2. The power supply apparatus according to claim 1, further comprising a buffer member that holds the battery pack and is disposed between the battery pack case and the battery pack, wherein the buffer member includes a vertical passage formed in a concave groove shape so as to extend in a vertical direction of the battery pack case between the buffer member and the battery pack case, wherein the vertical passage is defined by the gap between the battery pack case and the battery pack, andwherein the ventilation hole is located in each of an upper portion and a lower portion of the vertical passage. 3. The power supply apparatus according to claim 1, wherein a buffer member that holds the battery pack is disposed between the battery pack case and the battery pack, the buffer member is formed with a vertical passage on each of a front surface and a rear surface thereof, the vertical passage being formed in a concave groove shape so as to extend in a vertical direction of the battery pack case between the buffer member and the battery pack case, the vertical passage being defined as the predetermined gap between the battery pack case and the battery pack, and upper portions of the vertical passages are communicated with each other by a horizontal passage while lower portions thereof are communicated with each other by a horizontal passage, the vertical passages and the horizontal passages form a circulation passage so as to circulate gas therethrough, and the ventilation hole is located in each of an upper portion and a lower portion of the circulation passage. 4. The power supply apparatus according to claim 2, wherein the buffer member is an independent foamed material having elasticity. 5. The power supply apparatus according to claim 4, wherein the external electrical device is an electric outboard motor, and the electric power is supplied from the battery pack via the cable to an electric motor included in the electric outboard motor. 6. The power supply apparatus according to claim 1, wherein the cover member is connected to the case body by a hinge so as to open and close the opening of the case body,wherein the cable is divided into an internal cable section that is connected to the battery pack and extends in the case body to the cover member, and an external cable section that extends from the cover member to the external electrical device,wherein the internal cable section includes a horizontal portion and a vertical portion,wherein the horizontal portion is connected to the battery pack and extends in a substantially horizontal direction along a bottom surface of the case body,wherein the vertical portion extends in the case body upward from the horizontal portion to the cover member and includes a play portion that is moved with an opening and closing action of the cover member, andwherein the cable housing portion that houses the vertical section is provided in a range between the bottom surface of the case body and the cover member inside of the case body. 7. The power supply apparatus according to claim 6, wherein the battery pack is held by a buffer member disposed between the battery pack case and the battery pack, and the horizontal portion of the internal cable section is immovable while being sandwiched between the buffer member and the case body, whereas the vertical section thereof is movable or deformable inside of a space of the cable housing portion. 8. The power supply apparatus according to claim 7, wherein the cover member closes the opening of the case body so as to make the case body liquid tight using a liquid-tight seal material provided with respect to the cable. 9. The power supply apparatus according to claim 8, wherein the horizontal portion of the internal cable section includes a pair of stand-up portions that stand upward in both end portions thereof, wherein one of the stand-up portions is connected to the battery pack, and another one of the stand-up portions is coupled to the vertical portion of the internal cable section. 10. The power supply apparatus according to claim 9, wherein the external electrical device is an electric outboard motor, and the electric power is supplied from the battery pack via the cable to an electric motor included in the electric outboard motor. 11. The power supply apparatus according to claim 1, wherein an electric power take-out section of the power supply apparatus that supplies the electric power therefrom to the electric outboard motor is provided on the one side surface of the outer wall of the case main body of the battery pack case on which the carrying handle is provided. 12.
