In a power control unit provided in this application, a reactor (38) and a DC/DC converter (step-down transformer) (24) are stacked, and a capacitor (40) is arranged next to these. The capacitor (40) is fixed at fixing points (a cradle (90) and a fixing protrusion (88)) in two locations, and is also fixed to the DC/DC converter (24) by a bus bar (104) that electrically connects a terminal (78) of the capacitor to a terminal (100) of the DC/DC converter. A fixing position by the bus bar (104) is a position away from a straight line that passes through the fixing points in two locations, which is advantageous for suppressing vibrations around this straight line.
