ELECTRIC POWER CONVERSION APPARATUS

In an electric power conversion apparatus, a semiconductor module-cooler unit includes a semiconductor module and a cooler that has cooling pipes stacked with the semiconductor module in a stacking direction. A flow path forming component includes an electronic component main body and has an in-component flow path formed therein. A case receives both the semiconductor module-cooler unit and the flow path forming component therein. A pressure-applying member is arranged in the case to apply pressure to the semiconductor module-cooler unit from a rear side toward a front side in the stacking direction. Moreover, the flow path forming component is fixed to the case. The pressure-applying member, the semiconductor module-cooler unit and the flow path forming component are arranged in alignment with each other in the stacking direction. An in-cooler flow path formed in the cooler and the in-component flow path are fluidically connected with each other in the stacking direction.
