PROBLEM TO BE SOLVED: To provide an electric power conversion apparatus which achieves high cooling effect with a simple and small structure.SOLUTION: An electric power conversion apparatus 1 includes at least one of a filter capacitor 5, a smoothing capacitor 8, and a snubber capacitor 9 and a semiconductor element 7. The capacitor is formed by a capacitor module having capacitor cells 13, 13a, 13b, 13c and a capacitor case 15. One of or both of a P bus bar 11 and an N bus bar 12, which are connected with the capacitor cells 13, 13a, 13b, 13c, extend, and protrude to the exterior of the capacitor case 15, contact with an internal surface of the capacitor case 15 through an insulation material 16. |
