Claims

[Scope of utility model registration request]

A distal end component at the distal end of the insertion portion is covered with a distal end cover having a non-circular cross section, and a covering member that is adjacent to the rear end side of the distal end cover and covers an outer periphery of a curved portion of the distal end component. In the endoscope in which the covering member is fixed in close contact with the distal end component, the cross-sectional shape of the distal end portion of the covering member fixing portion for fixing the covering member to the distal end constituent portion, and the cross-sectional shape of the rear end portion of the distal end cover, An endoscope characterized by being substantially similar.
