PROBLEM TO BE SOLVED: To provide a separator for a solid polymer fuel cell capable of assuring gas impermeability, and to provide an efficient manufacturing method for it. SOLUTION: A separator 2 of a fuel cell 1 is conductive and composed of a resin mold comprising thermo-setting resin and carbon powder. The separator 2 is provided with a rib 12 and a fluid path 13 by press-molding. A density variation reducing member 21 comprising dense material is embedded in a part of the separator 2 which corresponds to the rib 12. |
