ENDOSCOPE, AND PRODUCTION METHOD AND REPAIR METHOD FOR THE SAME

摘要

An endoscope, and a production method and a repair method for the endoscope, where an illuminating lens whose front end surface is exposed from an opening at the head of an insertion section and whose rear end surface is in contact with or close to the front end surface of a light guide can be replaced without damaging the light guide in contact with the illuminating lens. An endoscope having an illuminating lens (33a) fitted in a frame (33d) which is installed at the head of an insertion section and whose adhesion section (33ac) at its outer periphery is fixed in the frame (33d) by an adhesive agent (100) and having a light guide (33b) installed in the frame (33d) such that an emission end surface (33bs) is in contact with a curvature surface (33ak) of the illuminating lens (33a), wherein a non-adhesion section (70) is formed between the adhesion section (33ac) of the illuminating lens (33a) in the frame (33d) and the emission end surface (33bs) of the light guide.
