PROBLEM TO BE SOLVED: To provide an endoscope capable of achieving connection and electric conduction between a distal body and a distal joint piece by a simple configuration without enlarging the distal end.SOLUTION: First and second notches 46 provided on a peripheral wall in a distal side are bent in the inside diameter direction so as to form a locking claw 46 at a distal joint piece 30A. A keyway 47 shallower than the protrusion length in the inside diameter direction of the locking claw 46 is provided at a distal body 20, so that, when the distal joint piece 30A is engaged with the distal body 20, the locking claw 46 is inserted into the keyway 47 to be engaged with each other in an elastically deformed manner.
