ABSTRACT:
A cylindrical grip member is connected to a back end of a body of an operation section at hand. The grip member is connected to face forward so that its axis can be at an acute angle against an axis of the back end of an insertion section. As for the grip member, it is possible to keep the body of the operation section horizontal if the grip member is held by a wrist in a natural way. Therefore, when this endoscope is used, the extra force does not have to be added to the wrist during observation. And, in the case that an angle formed by the body of the operation section and the grip member is set at 20.degree.-45.degree., it is possible to hold the grip member in such a manner that an arm holding the grip member is put against the side of a human body, that is, the underarm is tightened, so the body of the operation section can be stably supported.
