Abstract

An endoscope includes an insertion portion including a bending portion, an operation portion including an operation lever, a grasping portion including an actuator, and a tube body, in a continuous manner. When the operation lever is tilted, the actuator pulls a wire, whereby the bending portion is bent in a vertical direction and a lateral direction. The actuator is arranged such that a center of gravity of a portion including the insertion portion, the operation portion, the grasping portion, and the tube body is within a range in which at least one of the fourth finger or the fifth finger of the hand grasping the grasping portion is positioned, in a longitudinal direction of the grasping portion.
