The endoscope to be provided on Tip side of the bend, to consist of the insulating Characteristic resin component which facilities makes as one unit shift the Tip hard component and the Tip hard component of the metal make where, the observation optical department is done facilities shift be laid out in the transparent illumination window part and inside the Tip cover and it possesses the luminous element distribution facilities hole luminous element distribution facilities hole which forms illumination optical department, you facing to the illumination window part which the Tip cover has, from the aperture of the light-emitting part and the said luminous element distribution facilities hole which are locked to the position where it decides beforehand be located on illumination window part side, the aperture of the said luminous element distribution facilities holeAs it possesses the luminous element and the thermal conductivity which have the continuity section which opposes is jointed to the continuity section of the luminous element, it possesses the substrate and the thermal conductivity which combine the heat dissipation component where the cable for power source which supplies power source is jointed, one end side is jointed by the substrate, the heat which other end side extends from the substrate, conducts in the said substrate is possessed the tabular heat dissipation component which releases heat and.内視鏡は、湾曲部の先端側に設けられ、観察光学部が固設される金属製の先端硬性部材と、先端硬性部材に一体に固設される絶縁性の樹脂部材で構成され、照明光学部を構成する透明な照明窓部及び発光素子配設穴を有する先端カバーと、発光素子配設穴内に配置され、先端カバーの有する照明窓部に臨まれて予め定めた位置に固定される発光部及び該発光素子配設穴の開口より照明窓部側に位置し、該発光素子配設穴の開口に対向する導通部を備える発光素子と、熱伝導性を有し、発光素子の導通部に接続されるとともに、電源を供給する電源用ケーブルが接続される放熱部材を兼ねる基板と、熱伝導性を有し、基板に一端側が接続され、他端側が基板より突出し、該基板に伝導された熱を放熱する板状の放熱部材と、を具備する。
