PROBLEM TO BE SOLVED: To provide a compact exothermic body fixation structure which efficiently cools an exothermic body such as a semiconductor module.SOLUTION: There is provided an exothermic body fixation structure between the exothermic body, which includes two planes facing each other to configure at least one cooling surface, and a cooler which includes: a pair of heat receiving plates respectively disposed to cover the two planes; an elastic member disposed in a region in which the pair of heat receiving plates face each other; and slots to which the exothermic body and the pair of heat receiving plates are inserted, so as to cool the pair of heat receiving plates. When the exothermic body and the pair of heat receiving plates are inserted into the slots, pressing force to make the pair of heat receiving plates contact to the inner wall faces of the slots is loaded by the elastic member.SELECTED DRAWING: Figure 9 【課題】半導体モジュール等の発熱体を効率よく冷却するとともに小型な発熱体の固定構造を提供する。【解決手段】対向する二平面を有し、二平面は少なくとも一の冷却面である発熱体と、二平面をそれぞれ覆うように設けられる一対の受熱板と、一対の受熱板が互いに対向する領域に設けられる弾性部材と、発熱体および一対の受熱板を挿入するスロットを有し、一対の受熱板を冷却する冷却器と、発熱体および一対の受熱板をスロットに挿入した場合に、弾性部材によって、一対の受熱板がスロットの内壁面に当接するような押圧力が負荷される発熱体の固定構造【選択図】図９
