Abstract
An electric power converter has a semiconductor module that has a switching element therein, cooling pipes that contact with heat radiating surfaces of the semiconductor module and cool the semiconductor module, and a capacitor module formed by sealing a capacitor element therein by a potting material. A piled unit is formed by piling the semiconductor module and the cooling pipes. A direction in which the semiconductor module and the cooling pipes are piled is defined as a piling direction. The piled unit is sandwiched between the capacitor module disposed in a first end side in the piling direction of the piled unit and a pressing member disposed in a second end side in the piling direction of the piled unit. The first end of the piled unit is contacted to a potting surface that is a surface of the potting material in the capacitor module.
