PROBLEM TO BE SOLVED: To provide a heat exchanger having high heat exchanging performance and being suitably used as an evaporator. SOLUTION: A group of heat exchange pipes 5 of two or more rows composed of a plurality of heat exchange pipes, is mounted between a refrigerant flow in/out-side tank 2 and a refrigerant turn-side tank 3. The inside of a refrigerant inlet header chamber 13 of the refrigerant flow in/out-side tank 2 is divided into two spaces 13a, 13b in the height direction by a shunt resistance plate 25. The heat exchange pipes 4 are connected with the refrigerant flow in/out-side tank 2 in a state of being faced to the first space 13b. One refrigerant passing hole 27 is formed on a central part in the longitudinal direction of the shunt resistance plate 25. The refrigerant flowing into the second space 13a of the refrigerant inlet header chamber 13 of the refrigerant flow in/out-side tank 2 enters into the first space 13b through the refrigerant passing hole 27, flows into the refrigerant turn-side tank 3 through the heat exchange pipes 4, and then changes its flowing direction to flow into a refrigerant outlet header chamber 14 of the refrigerant flow in/out-side tank 2 through the heat exchange pipes 4.
