An endoscope has a first bending portion, a second bending portion, and a hand-held unit. The first bending portion is the distal portion of an elongated insertion member. The second bending portion is located at the proximal end of the first bending portion. The hand-held unit is located at the proximal end of the insertion member and has a control section that is used to bend the first bending portion and second bending portion. In the endoscope, the control section of the hand-held unit includes a bending knob, a second bending lever, a first locking lever, and a second locking lever. The angling knob is used to bend the first bending portion, and the second angling lever is used to bend the second bending portion. The first locking lever is used to lock the angling knob at a predetermined angular position, and the second locking lever is used to lock the second angling lever at a predetermined angular position.
