PROBLEM TO BE SOLVED: To provide a heat exchanger having high heat exchanging performance when it is 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 4, is mounted between a refrigerant flow in/out-side tank and a refrigerant turn-side tank 3. The inside of the refrigerant flow in/out-side tank is divided into a refrigerant inlet header chamber and a refrigerant outlet header chamber. The inside of the refrigerant turn-side tank 3 is partitioned into a refrigerant inflow-side header chamber 32 and a refrigerant outflow-side header chamber 33 by a shunt control plate 44. Refrigerant stopping parts 45A, 45B are formed on both end parts of the shunt control plate 44. A refrigerant passing part 46 having one or more refrigerant passing holes 43 is mounted between the both refrigerant stopping parts 45A, 45B. The refrigerant flowing into the refrigerant inlet header chamber of the refrigerant flow in/out-side tank flows into the refrigerant inflow-side header chamber 32 of the refrigerant turn-side tank 3 through the heat exchange pipes 4, enters into the refrigerant outflow-side header chamber 33 through the refrigerant passing holes 43, and changes its flowing direction to flow into the refrigerant outlet header chamber of the refrigerant flow in/out-side tank through the heat exchange pipes 4.
