PROBLEM TO BE SOLVED: To provide a heat exchanger comprising a liquid receiver capable of efficiently separating a gas-phase refrigerant and a liquid-phase refrigerant, and allowing the separated liquid-phase refrigerant to efficiently flow out from a refrigerant outflow port. SOLUTION: A refrigerant inflow port 31 and the refrigerant outflow port 32 are formed on a peripheral wall of a cylindrical main body 26 of the liquid receiver 7 of this heat exchanger in such a state that the former is positioned at an upper part. The liquid receiver 7 is provided with a baffle plate 33 positioned on a part between the refrigerant inflow port 31 and the refrigerant outflow port 32, and a swirl flow generating device 34 positioned at an upper part with respect to the baffle plate 33, guiding the refrigerant flowing in from the refrigerant inflow portion 31 to an axial side of a cylindrical main body 26 while swirling the refrigerant, and sending the refrigerant upward. The swirl flow generating device 34 is composed of a guide member 37 applying swirling motion to the refrigerant, and having a hollow portion 39 communicating the refrigerant inflow port 31, an upper part of the swirl flow generating device 34 and a lower part of the baffle plate 33.
