PROBLEM TO BE SOLVED: To provide an electric power conversion system which enables further improvement of the cooling efficiency of a capacitor element.SOLUTION: A capacitor 2 includes: a capacitor element 21; an electrode part 22; and a bus bar 23. The capacitor element 21 has: a dielectric substance 210; and a metal layer 211 formed on a surface of the dielectric substance 210. The electrode part 22 is formed on the capacitor element 21 and connected to the metal layer 211. The bus bar 23 includes a bottom part 25 and a protruding part 26. The bottom part 25 is connected to a major surface S1 of the electrode part 22 which is opposite to a side connected to the metal layer 211. The protruding part 26 is erected from the bottom part 25 in a thickness direction of the bottom part 25. The electrode part 22 is fitted in a recessed part 239 formed by the bottom part 25 and the protruding part 26. A part of the bus bar 23 is disposed between the electrode part 22 and the heat radiation member 3.SELECTED DRAWING: Figure 1 |
