A cooling device for a vehicle, includes a cooling circuit including a first circuit in which a cooling liquid circulates through a power control unit and a second circuit connected in parallel with the first circuit and in which the cooling liquid circulates through a battery without passing through the power control unit; and a flow-rate control unit that controls a proportion of a flow rate of the cooling liquid between the first circuit and the second circuit, and when the battery is being charged with the electric power of the external power supply, the control unit controls so that the flow rate of the cooling liquid flowing through the second circuit is greater than the flow rate of the cooling liquid flowing through the first circuit on a side of the power control unit.
