To provide an endoscope capable of maintaining the fine operability at the time of insertion, and selecting a different bending direction of the bending radius when necessary.

The endoscope 1 comprises an insertion part with a bending part to be bent in a plurality of directions and an operation part with a plurality of bending operation members 23 to operate the bending part of the insertion part. The length of bending of the bending part operated by a bending operation member 23A near a grip part 3a of the operation part among the plurality of operation members 23 is longer in at least one bending direction than the length of bending operated by another bending operation member 23B in another bending direction. It is further preferable that the bending direction of the bending part operated by the bending operation member 23A near the grip part 3a is the direction of moving an observation image displayed in a monitor, a display means, in the direction of gravity or the opposite direction of gravity of the monitor.
