PROBLEM TO BE SOLVED: To provide an endoscope capable of efficiently radiating heat emitted from an LED by a constitution composed of a small number of components.SOLUTION: The endoscope includes: an insertion part 2 an operating part 3 connected to the proximal end of the insertion part and a circuit board 32 which is disposed inside the operating part and in which the LED is mounted. The endoscope has such a constitution that the light emitted from the LED is guided to the distal end of the insertion part by using an optical fiber bundle to be used as illumination light. The endoscope further includes a first heat radiation part 51 in contact with the mounted surface of the circuit board and a second heat radiation part 52 in contact with the opposite surface from the mounted surface of the circuit board. The first heat radiation part is joined to the second heat radiation part with the circuit board held in-between. The first and second heat radiation parts joined to each other are support members joining a structure on the distal end side of the operating part to a structure on the proximal end side of the operating part.COPYRIGHT: (C)2013,JPO&INPIT【課題】少ない部品構成でLEDが発する熱を効率良く放熱することができる内視鏡を提供する。【解決手段】挿入部2、挿入部の基端側に接続された操作部3、及び操作部内に配設されLEDが実装された回路基板32を具備し、LEDが発する光を光ファイバ束を用いて挿入部の先端部へ導光して照明光として用いる構成を有する内視鏡であって、回路基板の実装面上に接する第1放熱部51と、回路基板の実装面とは反対側の面上に接する第2放熱部52と、を具備し、第1放熱部及び第2放熱部は、回路基板を挟持した状態で結合されており、互いに結合された第1放熱部及び第2放熱部は、操作部の先端側構造部と、操作部の基端側構造部とを結合する支持部材となることを特徴とする。【選択図】図11
