摘要：
PROBLEM TO BE SOLVED: To efficiently radiate heat while superimposing a photographing field angle in a perspective direction and an irradiation range, to suppress the temperature of a hard part surface within a safe range, and to suppress an increase in occupied volume of a heat radiating structure. A perspective endoscope is provided at a distal end of a scope, and has a rigid portion in which an inclined end surface that is inclined with an acute included angle to an axis of the scope is formed, and a rigid portion. A camera whose axis is substantially perpendicular to the slanted end face, a self-luminous body that is internally provided in the rigid portion and emits illumination light from the slanted end face, and a self-luminous body that is formed substantially parallel to the slanted end face and is mounted with self-luminous light A primary heat transfer body having a heat receiving surface through which heat generated from the body is transmitted and having a heat conducting portion extending from the heat receiving surface in a direction along the optical center axis. [Selection diagram] Fig. 5A【課題】斜視方向の撮影画角と照射範囲を重ね合わせつつ効率的な放熱が行え、硬性部表面の温度を安全な範囲に抑制し、かつ放熱構造の占有体積の増大を抑制する。【解決手段】斜視内視鏡は、スコープの先端に設けられ、スコープの軸線に鋭角の挟角を有して傾斜する傾斜端面が形成される硬性部と、硬性部に内設され、光学中心軸が傾斜端面に略垂直となるカメラと、硬性部に内設され、傾斜端面から照明光を出射する自発光体と、傾斜端面と略平行に形成されて自発光体を実装し、自発光体からの発熱が伝わる受熱面を有するとともに、受熱面から光学中心軸に沿う方向に延在する熱伝導部を有する一次伝熱体と、を備える。【選択図】図５Ａ
