PROBLEM TO BE SOLVED: To provide a heat exchanger in which width of a tank part is small.SOLUTION: A heat exchanger 10 includes a core plate 24 and a tank member 27. In the core plate 24, a plurality of claws 35 are formed. The claw 35 has a taper shape. A wave-like wall 45 is formed at the tank member 27. An outer valley part 43b receives the claw 35. The claw 35 comes into contact with a step part 42. On the inner side of the outer valley part 43b, an inner ridge part 44a is provided. The inner ridge part 44a is positioned between two tubes 22 adjacent to each other. A part of the inner ridge part 44a is positioned to overlap with the tube 22 regarding the length direction. The core plate 24 and the tank member 27 are connected by a caulking part including the claw 35. The wave-like wall 45 can reduce width of the tank part by suppressing interference between the tank member 27 and the tube 22 while maintaining the thickness of the wall of the tank member 27. |
