Abstract: A heat exchanger includes a stacked body that is configured by tubes stacked in a stacking direction and a header tank. The header tank includes a plate header and a tank body. The tubes include longitudinal ends attached to the plate header. The plate header includes a tube insertion hole provided with a stopper. One of the longitudinal ends of the plurality of tubes is inserted into the tube insertion hole. The stopper sets a position of the one of the longitudinal ends in the tube insertion hole. The stopper is provided with the tube insertion hole, and has a width dimension that is smaller than both of a width dimension of the tube insertion hole and a width dimension of the one of the longitudinal ends of the plurality of tubes when viewed in the stacking direction.

Abstract: A tank has a tank body defining a passage therein, a plate to which tubes are attached, and an intermediate plate. The tank body has a space defining part and a tank junction part attached to the intermediate plate. A longitudinal direction and a stacking direction of the tubes are perpendicular to a width direction. The space defining part has two end parts facing each other in the width direction and connecting to two of the tank junction part respectively. The tank body has a junction end surface that has an arc shape protruding toward the passage. The intermediate plate has a part corresponding to the junction end surface and being provided with a receiving surface that has an arc shape fitting the arc shape of the junction end surface. The receiving surface is attached to the junction end surface.
