Abstract
In an endoscope, a curvature indicating element for curvature-indicating a curvable curvature section provided adjacent to a distal end of an elongated inserting section having elasticity is arranged at a location close to a thumb of a hand grasped by an operator in the operating section provided at a proximal end portion of an inserting section. An operating element for controlling operation of fluid such as outflow, inflow or the like is arranged at location opposite to the curvature indicating element in the operating section. Thus, operations of the curvature operation, outflow and inflow of the fluid and the like can be executed simultaneously under a condition where the operating section is grasped.
