ABSTRACT:
In a heat exchanger according to the present invention, a projecting edge portion integrally projects outward from an opening edge portion of a tank body, and a tank and a core plate are connected to each other in such a way that a claw portion of an edge portion of the core plate is caulked by being folded toward a back of the projecting edge portion, and the back of the projecting edge portion at the opening edge portion of the tank body and an outside surface of the tank body are continuously connected to each other by a curved surface. Accordingly, stress dispersedly acts on the connection portion between the tank and the core plate so that local stress concentration is prevented and breakage is prevented.
