To provide a fuel cell capable of improving battery output by increasing a contact pressure between an electrode layer and a conductive layer such as a metal layer.

In the fuel cell, a laminate L including a solid polymer electrolyte layer 1, a first electrode layer 2 and a second electrode layer 3 arranged on its both sides, and a first metal layer 4 and a second metal layer 5 arranged on the outside of these is integrated with a resin molding 6. The first metal layer 4 or the second metal layer 5 has exposed portions 40, 50 which expose partially the surface of the first electrode layer 2 or the second electrode layer 3, and the resin molding 6 has a supply portion 60 for supplying gas or liquid to the first electrode layer 2 or the second electrode layer 3 through the exposed portions 40, 50, and has a contact portion 6a which contacts a part of the first electrode layer 2 or the second electrode layer 3 exposed from the exposed portions 40, 50.
