Abstract
A power module constructs a pressurizing tool by laminating an elastic member as well as a DC positive-side wiring member and DC negative-side wiring member in which currents flow in opposite directions. The pressurizing tool presses a first fixing tool, and then the first fixing tool presses semiconductor equipment. The semiconductor equipment is fixed to a heat dissipating member with its heat dissipating surface brought into surface contact with side wall surfaces of the heat dissipating member. The power module can enhance heat dissipation between a heat dissipating member and semiconductor equipment, and enables the semiconductor equipment to be fixed to the heat dissipating member without adding other components to the power module.
