PROBLEM TO BE SOLVED: To provide a heat exchanger capable of further homogenizing a discharged air temperature in a case of being used as an evaporator. SOLUTION: This evaporator 1 includes a refrigerant inlet header portion 5 having a refrigerant inlet 8 at its right end, and a plurality of heat exchange tubes 16 connected to the refrigerant inlet header portion 5. The inside of the refrigerant inlet header portion 5 is divided into first and second spaces 35, 36 by a partitioning portion 37 in a state of being vertically arranged. The refrigerant inlet 8 is communicated with the first space 35, and heat exchange tubes 16 face the second space 36. A refrigerant flows into the second space 36 from the first space 35 through a communicating port 48 formed on a part at a left end side of the partitioning portion 37. The communicating port 48 is constituted of a through elongate hole 49 formed on the partitioning section 37 and extending to the refrigerant inlet 8 side from a part at a left side with respect to the heat exchange tube 16 positioned on a left end. A plurality of, for example, three heat exchange tubes 16 as a part of the total heat exchange tubes 16 are disposed within a range in the longitudinal direction, of the elongate hole 49.
