PROBLEM TO BE SOLVED: To secure brazing performance of a corrugate fin and a tube in a heat exchanger having a deformed part on a side plate for absorbing the difference in thermal expansion between the tube and the side plate. SOLUTION: A stopper 420 is mounted on the side plate 4 for preventing the deformation of the deformed part 410 in the tube stacking direction Y. As the deformation of the deformed part 410 can be prevented by the stopper 420 in integral brazing, that is, the warpage of the side plate 4 can be prevented, the corrugate fin 11 can be surely pressed and the brazing performance of the corrugate fin 11 and the tube can be secured in integral brazing.
