A vehicle (100) includes a motor housing (90) accommodating motors (91a, 91b) for driving wheels, and a power control unit (2, 102, 202) fixed on the motor housing (90). The power control unit (2, 102, 202) includes: a stacked unit (40) in which multiple power modules (6) accommodating power semiconductor elements for electric power conversion and multiple coolers (46) are stacked; and reactors (4a, 4b). The stacked unit (40) is disposed in the case (20) of the power control unit (2, 102, 202) such that the stacking direction of the power modules (6) and the coolers (46) is directed toward the vehicle-longitudinal direction. The reactors (4a, 4b) are disposed in the case (20) so as not to overlap with the stacked unit (40) as viewed from the stacking direction.
