RESIN FRAME EQUIPPED MEMBRANE ELECTRODE ASSEMBLY AND METHOD OF PRODUCING RESIN FRAME MEMBER FOR FUEL CELL

A resin frame member is produced by using a method of producing a resin frame member for a fuel cell. An inner peripheral end of the resin frame member includes an inclined surface formed over the entire periphery thereof. The inclined surface is inclined inward from one surface of the resin frame member toward the other surface of the resin frame member. The width of the inclined surface is gradually reduced from the center toward both ends of each side part of the inner peripheral end in a direction in which the side part of the inner peripheral end extends.
