In a drive unit including a motor (32), an inverter (34), a first electric storage device (36), a step up-down converter (40), a first capacitors (46) and a second capacitors (48), a DC-DC converter (54), and a relay (SMR), the DC-DC converter (54) is driven, while a target duty ratio of the step up-down converter (40) is set such that a total loss of the step up-down converter (40) and the DC-DC converter (54) becomes greater than a maximum loss value of the step up-down converter (40), and the step up-down converter (40) is controlled, when the relay (SMR) is turned off to discharge charge of the first capacitor (46) and the second capacitor (48).
