PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing a ratio of a gas phase refrigerant of a gas-liquid mixed phase refrigerant made to flow from a liquid receiver into a supercooling part. SOLUTION: The heat exchanger includes a pair of tanks 2, a plurality of heat exchange pipes 4 and the liquid receiver 7 mounted to either one of the tanks 2, and a condensation part 11 and the supercooling part 12 are juxtaposed vertically. A refrigerant made to flow out from a most downstream side header 13 of the condensation part 11 is made to enter into the liquid receiver 7, and a refrigerant made to flow out from inside of the liquid receiver 7 is made to flow in to a most upstream side header 16 of the supercooling part 12. In the supercooling part 12, a plurality of paths 21, 22 formed of the plurality of heat exchange pipes 4 are juxtaposed vertically. A refrigerant flowing pipe 35 communicating the most downstream side header 13 of the condensation part 11 with inside of the liquid receiver 7 is provided and arranged in a position capable of performing heat exchange between a refrigerant made to flow inside the refrigerant flowing pipe 35 with a refrigerant made to flow in a most downstream side header 17 of the supercooling part 12.
