1. A fire-extinguishing bomb, comprising: an outer casing defining therein an inner space isolated from the outside;an extinguishant storage part installed in the outer casing, the extinguishant storage part having an open top covered with a mesh cover, and having closed side and bottom walls, and containing an extinguishant that is contained in a solid state and is burnt at a predetermined burning point or higher;a mesh inner casing placed in the outer casing at a location above the extinguishant storage part such that the inner casing is spaced apart from an inner surface of the outer casing, with a coolant contained in the inner casing;a sealed inner casing holder connecting the inner casing to the inner surface of the outer casing such that the inner casing is fixed to the inner surface of the outer casing; andan ignition unit for igniting the extinguishant contained in the extinguishant storage part, wherein a plurality of ejection holes formed through an upper part of the outer casing which is placed above the inner casing holder, the ejection holes formed thoroughly from the inner surface to an outer surface of the outer casing. 2. The fire-extinguishing bomb as set forth in claim 1, wherein the outer casing is formed as a tubular structure and an upper part of the outer casing above the inner casing holder is formed as a dome shape. 3. The fire-extinguishing bomb as set forth in claim 1, wherein the outer casing comprises: a head that is formed as a dome shape at an upper part of the outer casing above the inner casing holder; and a tubular body that is formed at a part of the outer casing below the inner casing holder, whereinthe ejection holes are formed in the head, whereinthe ejection holes are formed along a plurality of circumferences of the head which are spaced apart from each other at regular intervals based on a peak of the head. 4. The fire-extinguishing bomb as set forth in claim 3, wherein the ejection holes that are formed thoroughly from the inner surface to the outer surface of the head are formed such that the ejection holes are directed gradually downward as locations of the ejection holes move downward from the peak of the head, so extinguishing gas generated from a burning of the extinguishant is ejected to all directions through the perforated head. 5. The fire-extinguishing bomb as set forth in claim 1, further comprising: a cover holder having a sealed structure, the cover holder connecting the cover to the inner surface of the outer casing, thereby fixing the cover to the inner surface of the outer casing. 6. The fire-extinguishing bomb as set forth in claim 1, wherein the coolant comprises solid particles having a predetermined size or greater. 7. The fire-extinguishing bomb as set forth in claim 1, wherein the extinguishant comprises a solid aerosol material. 8. The fire-extinguishing bomb as set forth in claim 7, wherein the solid aerosol comprises 45 to 80 wt % of potassium nitrate (KNO3), 15 to 50 wt % of epoxy resin, 0.5 to 5 wt % of surfactant, and 0.5 to 5 wt % of catalyst. 9. The fire-extinguishing bomb as set forth in claim 1, wherein the ignition unit comprises: a detonating part placed in the extinguishant contained in the extinguishant storage part; anda triggering part that heats the detonating part to a predetermined burning point or higher, whereinthe extinguishant is burnt by heat of the detonating part heated by the triggering part. 10. The fire-extinguishing bomb as set forth in claim 9, wherein the detonating part comprises a hot wire or a resistance material that is heated to a predetermined burning point or higher by an electric current having a predetermined intensity or greater, the detonating part being placed in the central portion of the extinguishant contained in the extinguishant storage part, andthe triggering part supplies an electric current having the predetermined intensity or greater to the hot wire or to the resistance material, thereby heating the hot wire or the resistance material so as to detonate and burn the extinguishant by heat of the hot wire or of the resistance material. 11. The fire-extinguishing bomb as set forth in claim 10, wherein the triggering part and the detonating part are electrically connected to each other using a detonation wire. 12. The fire-extinguishing bomb as set forth in claim 10, further comprising: a mode selecting unit that is used to select an operational mode of the ignition unit between an activated triggering mode in which the detonating part is electrically connected to the triggering part such that the triggering part can supply the electric current to the detonating part, and an inactivated triggering mode in which an electric connection between the triggering part and the detonating part is cut off; anda timer that controls the triggering part such that the triggering part supplies the electric current having the predetermined intensity or greater to the detonating part just after a preset period of time has passed in a state in which the mode selecting unit has selected the activated triggering mode. 13. The fire-extinguishing bomb as set forth in claim 10, wherein the triggering part further comprises: a battery that stores electric energy so as to supply the electric current having a predetermined intensity or greater.
