PROBLEM TO BE SOLVED: To prevent improper brazing such as the occurrence of crack in a brazed part of a joint. SOLUTION: The joint 12 is brazed to an evaporator 1 on two faces of an upper side tank 11 and a heat exchange core part 4. Consequently, when moment acts on the joint 12 when performing brazing, force for increasing contact facial pressure acts on either of a join face 12a and a join face 12b. As a result, even if moment due to self-weight of the joint 12 or moment due to positional deviation of a holding tool when holding the joint 12 acts on the joint 12, it is possible to prevent the occurrence of improper brazing such as the occurrence of crack in the brazed part of the joint 12.
