Description of the Related Art A conventional heat exchanger is known in which a tank element having a tank communication hole is provided in a tube element, and the tank element is laminated to form a tank by communicating the tank element of the tube element. (For example, see Japanese Utility Model Application Laid-Open No. 61-89686).

していた。In the prior art, end plates are disposed on both sides of the tube elements at both ends in the stacking direction in order to close the tank communication holes of the tank portions of the tube elements at both ends in the stacking direction. And, at the portions corresponding to the tank portion communication holes of the tank portions of the tube elements at both ends in the laminating direction that are in contact with this end plate, the end plate is prevented from being deformed by the pressure received from the tank and causing airtight leakage. For this purpose, a reinforcing projection having a flat cross section is provided, and the projection is fitted into a corresponding communication hole of the tank portion to reinforce the end plate.

Or, if the formation positions of the projections are shifted, there is an inconvenience that a position shift occurs between the tube element and the end plate.
