PROBLEM TO BE SOLVED: To provide an electric power conversion apparatus which reduces the number of components thereby enabling the downsizing and the reduction of the man hours in the manufacturing process.SOLUTION: An electric power conversion apparatus 1 includes: a semiconductor module 2 incorporating a switching element 21 therein; a cooling tube 3 which contacts with a heat radiation surface 24 of the semiconductor module 2 thereby cooling the semiconductor module 2; and a capacitor module 4 which is formed by sealing a capacitor element 41 with a potting material 42. A laminated body 10 formed by laminating the semiconductor module 2 on the cooling tube 3 is held in a lamination direction Z by the capacitor module 4 disposed at the one end side in the lamination direction Z and a pressing member 5 disposed at the other end side in the lamination direction Z. One end of the laminated body 10 is in contact with a potting surface 43 which is a surface of the potting material 42 in the capacitor module 4. |
