PROBLEM TO BE SOLVED: To secure a heat radiation pathway for an imaging device housed within an endoscope distal end, and to reinforce the imaging device.SOLUTION: An electronic endoscope apparatus includes an endoscope including: an imaging device 23 connected to a processor device for processing image signals light guides 40a and 40b for guiding illumination light from a light source device to emit it into a subject through an illumination window and a forceps pipe 16 inserted to a forceps outlet, which are housed in a distal end part 12a. The rear surface of the imaging device 23 is closely fixed to the outer peripheral surface of the forceps pipe 16 with an adhesive 41 to make the forceps pipe 16 serve as a heat radiation pathway for the imaging device 23. With this structure, the forceps pipe 16 can be also used as a reinforcing member for the imaging device 23 at the same time.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】 内視鏡スコープ先端部内に収納される撮像素子の放熱経路の確保と撮像素子の補強を図る。【解決手段】 画像信号処理を行うプロセッサ装置に接続される撮像素子23と、光源装置からの照明光を通し照明窓から被検体内に照射するライトガイド40a,40bと、鉗子出口まで挿通される鉗子パイプ16とが先端部12a内に収納される内視鏡スコープとを備える電子内視鏡装置において、撮像素子23の裏面を鉗子パイプ16の外周面に接着材41で密着固定し、鉗子パイプ16を撮像素子23の放熱経路とする。これにより、同時に、鉗子パイプ16を撮像素子23の補強部材として利用可能となる。【選択図】 図5
