A heat exchanger according to the present disclosure includes a main heat exchange unit configured to exchange heat between air and refrigerant, and condense the refrigerant, a subcooling heat exchange unit configured to exchange heat between air and the refrigerant passing through the main heat exchange unit, and subcool the refrigerant passing through the main heat exchange unit, and a connection pipe configured to connect the main heat exchange unit and the subcooling heat exchange unit to allow the refrigerant to pass therethrough, wherein the connection pipe connects the main heat exchange unit on its outflow side to the refrigerant and the subcooling heat exchange unit on its inflow side to the refrigerant, such that when the main heat exchange unit condenses the refrigerant, the refrigerant from the outside flows into the downstream side of the main heat exchange unit and the subcooling heat exchange unit relative to a flow of the air, and flows out from the upstream side of the main heat exchange unit and the subcooling heat exchange unit relative to a flow of the air to form a counter flow in which a flow of the refrigerant is opposite to a flow of the air.
