End plates, as constituting elements in a fuel cell, are conventionally made by cutting metal plates. Therefore, they have problems in that it is difficult to reduce their cost, and they are inconveniently heavy, and that they are likely to be corroded by supplied gases and cooling water since they contact such gases and water at inside surfaces of manifold holes of the metal end plates. According to the present invention, the end plates are made of a resin-dominant material, more preferably by injection-molding such material, so that it becomes possible to reduce the cost and weight of the end plates, and the corrosion resistance can be greatly improved by insert-molding each of current collecting plates in each of the end plates in such a manner as for the end plate material to extend into an inside surface of a hole, to be a manifold hole, of each current collecting plate.
