Since the bent portion is not formed in the peripheral portion, the heat exchange tube insertion opening formed in the seat plate member is not likely to be deformed. Therefore, the distance between the opening for inserting the heat exchange tube at the end and the bent portion at the peripheral edge of the header member can be shortened. Therefore, according to the present invention, the tank of the heat exchanger can be made smaller than the tank of the conventional heat exchanger. A semicircular arc-shaped out-of-plane bend is formed in a part of the flange of the header member, and a substantially semicircular cutout is formed in a part of the side wall of the header member in opposition to the bend, and the inflow and outflow pipes are formed. When a pair of cylindrical openings having a substantially semicircular cross section for insertion is formed, the insertion height of the inflow pipe and the outflow pipe becomes lower than that in the case where the openings are circular, and the tank is The height is reduced and the tank is downsized. In the case where the header member is formed with a cutout extending between the side wall and the flange to form a pair of substantially semicircular openings for inserting the inflow and outflow pipes, compared to the case where the openings are circular. The insertion height of the inflow pipe and the outflow pipe is reduced, the height of the tank is reduced, and the tank is downsized.
