1. An endoscope, comprising:
- an insertion part to be inserted in a subject, a distal end portion of the insertion part having a projecting part receiving hole on a distal end face of the insertion part, an axis of the projecting part receiving hole being in a longitudinal direction of the insertion part, the projecting part receiving hole receiving a projecting part of a cap member attached on the distal end face of the insertion part, the distal end portion having an attachment hole on an outer periphery of the distal end portion, the attachment hole connecting with the projecting part receiving hole, the attachment hole receiving a fixing member fixing the projecting part of the cap member to the distal end portion;
the cap member which is attached on the distal end face of the insertion part, the cap member having the projecting part on a face of the cap member facing to the distal end face of the insertion part, the projecting part being inserted in the projecting part receiving hole of the distal end portion of the insertion part; and
a covering member which covers an outer periphery of the insertion part including an opening of the attachment hole on the outer periphery of the distal end portion of the insertion part.

Abstract
The insertion part of the endoscope has a cap fixed to the distal end face of a distal end body. A projecting part of the cap is inserted in a receiving hole formed on the distal end face. The inserted projecting part is fixed to the distal end body with a screw inserted in an attachment hole, which is formed on the periphery of the distal end body and connects with the receiving hole. Bending rubber covers the attachment hole as well as the outer periphery of the distal end body.
