PROBLEM TO BE SOLVED: To provide an endoscope capable of making an adhesion fixing range by an adhesive agent appropriate.SOLUTION: A protective tube is provided for fixing an optical fiber bundle in which a plurality of optical fibers are bundled for guiding emission light of a light source to a tip of an insertion part, at the tip side of the insertion part. The optical fiber bundle is inserted into the protective tube and predetermined length is pulled out in an irradiation direction side. A first adhesive agent having a high curing rate is coated at the portion of the predetermined length, the optical fiber bundle is returned into the protective tube and pulled out again, and the first adhesive agent is cured. A second adhesive agent is coated on the cured first adhesive agent, the optical fiber bundle is returned to the protective tube, and the second adhesive agent is cured. The second adhesive agent is prevented from soaking into a gap between each optical fiber, and a fixing range of the optical fiber bundle can be prevented from spreading by the second adhesive agent.COPYRIGHT: (C)2015,JPO&INPIT【課題】接着剤による接着固定範囲を適切化し得る内視鏡を提供する。【解決手段】光源の出射光を挿入部の先端に導くために複数本の光ファイバを束ねた光ファイバ束を挿入部の先端側で固定する保護管を設ける。保護管に光ファイバ束を挿入しかつ照射方向側に所定長出し、その部分に硬化速度の速い第1の接着剤を塗布し、光ファイバ束を保護管内に戻し、再度出して第1の接着剤を硬化させる。硬化させた第1の接着剤の上に第2の接着剤を塗布し、光ファイバ束を保護管内に戻して第2の接着剤を硬化させる。第2の接着剤が各光ファイバ間の隙間に染み込むことが阻止され、第2の接着剤による光ファイバ束の固定範囲が広がることを防止し得る。【選択図】図4
