PROBLEM TO BE SOLVED: To provide an electric power conversion system capable of downsizing a whole system without inhibiting a heat radiation path of a heating component.SOLUTION: In an electric power conversion system 1, a heat sink 60 includes a body part 62, and a radiation fin 64 on which the body part 62 is provided. The body part 62 includes a thick wall part, defining a heat radiation path 68, on which a heating component is mounted, and a thin wall part, provided outside of the heat radiation path 68, on which non-heating components 14, 18, 120 are mounted.SELECTED DRAWING: Figure 2 |
