Abstract: The endoscope of the present embodiment is so configured that the forceps port connected to the insertion section can be rotated by connecting, like “L”, the front section from which the insertion section extends and the rear housing section from which the cable extends, and the curving operation lever is placed at a middle position of the L-shaped connection. Thus, the front section serving as the first grasping section and the rear housing section serving as the second grasping section can be shifted to each other as a section to be grasped, and the positions of the curving operation lever and the forceps port and the positions of the fingers match irrespective of the grasping mode, with the result that the operation can be performed comfortably.
