PROBLEM TO BE SOLVED: To provide a hood for an endoscope, capable of efficiently irradiating a subject with illumination light emitted by an illumination optical system when mounted on a distal end portion of an insertion part.SOLUTION: For a hood 25 for an endoscope, in a cylindrical hood to be detachably mounted on a distal end portion of an insertion part of an endoscope including an illumination optical system 23 on a distal end face 17 of the insertion part 12, an inner peripheral side reflection surface 26, which is positioned in front of the distal end face of the insertion part when mounted on the distal end portion and has light reflectance higher than the reflectance at the other parts of the hood surface, is formed on an inner peripheral surface of the hood.COPYRIGHT: (C)2013,JPO&INPIT【課題】挿入部の先端部に装着したときに照明光学系が出射した照明光を被写体に効率よく照射することが可能な内視鏡用フードを提供する。【解決手段】。挿入部12の先端面17に照明光学系23を備える内視鏡の該挿入部の先端部に着脱可能に装着する筒状をなすフードにおいて、フードの内周面に、上記先端部に装着したときに挿入部の先端面より前方に位置し、かつ、光の反射率が該フード表面のその他の部位に比べて高い内周側反射面26を形成したことを特徴とする内視鏡用フード25。【選択図】図3
