PROBLEM TO BE SOLVED: To enhance the cooling performance of a bus bar 96 while maintaining the supporting performance of a capacitor 90.SOLUTION: A thin-plate shaped bus bar 96 supplying power to an inverter circuit and a capacitor 90 electrically connected to the inverter circuit are housed in an enclosure 110. In the enclosure 110, a coolant passage 114 in which a coolant flows is provided. The bus bar 96 is pressed and closely attached to a cooling surface 116 by fixing a capacitor supporting case 140 to the enclosure 110 with the bus bar 96 sandwiched between a bottom wall portion of the capacitor supporting case 140 for supporting the capacitor 90 and the cooling surface 116 of the enclosure 110 adjacent to the coolant passage 114. |
