In an air conditioner for a vehicle, in a heating operation for heating a vehicle compartment, when heating capacity is obtained by flowing a coolant through an inside of an indoor heat exchanger, the coolant flows directly in the inside of the indoor heat exchanger to heat air to be supplied to the vehicle compartment. In contrast, when the heating capacity is not obtained by flowing the coolant through the inside of the indoor heat exchanger, the coolant flows through a first water-refrigerant heat exchanger and a refrigerant in a heat pump cycle circulates so that heat of the coolant is absorbed by the refrigerant in the first water-refrigerant heat exchanger, and the air is heated in the indoor heat exchanger by using heat of the refrigerant that has absorbed the heat of the coolant.
