Abstract: There is provided an endoscope capable of realizing equal operability by either a left or right hand without upsizing an operation portion. For this purpose, an operation portion is formed in a bilaterally symmetrical shape; a suction button and a bending lever are disposed at a center in a left and right width direction of the operation portion facing each other; and respective arm portions are disposed in a state of being rotated around a central axis of the bending lever by a predetermined angle relative to up, down, left and right tilt directions defined for the bending lever.
