PROBLEM TO BE SOLVED: To provide an air conditioner capable of performing adjustment of a refrigerant amount by using a receiver without making a structure complicated, and which has high operation efficiency. ! SOLUTION: An air conditioner includes: a refrigerant circuit including a compressor 3, an indoor heat exchanger 7, a throttle device 5 and an outdoor heat exchanger 4; a receiver 13 for storing a refrigerant; and a connection pipe 14 for connecting the refrigerant circuit and the receiver 13. In the connection pipe 14, one end side is connected to a gateway 15 of the receiver 13 and the other end side is, in the refrigerant circuit, connected an area in which at least one part of a high pressure refrigerant discharged from the compressor 3 during a cooling operation exists as a liquid phase. The receiver 13 is provided so that it can exchange heat with piping 12 in which the refrigerant flows from the indoor heat exchanger 7 to the compressor 3 during the cooling operation. !
