In a laminated heat exchanger provided with tanks only on one side, which is constituted by laminating tube elements alternately with fins over a plurality of levels, a flange portion projecting out toward the fins is provided in each formed plate constituting the tube elements at an end portion on the opposite side from the tanks, and the flange portions facing opposite each other between the individual tube elements are made to face opposite each other over gaps. A notch is formed in each flange portion. For different types of formed plates, the notches are at positions shifted relative to one another in the direction of the width of the core main body along the direction of airflow. A notch may be formed at any position and be of any size in the flange portion. When assembling different types of tube elements, even if there are many different types of tube elements, the likelihood of erroneous assembly is reduced and, moreover, the likelihood of erroneous judgment through visual inspection or the use of a detection device can be reduced. |
