In order to achieve cost reduction for fuel cell stacks, gaskets (1 (2)) for a fuel cell are formed integrally by a rubber-like elastic material in the outer periphery of GLDs (3 (4)), which are interposed between separators (6 (7)) and an MEA (5), and are in close contact with the separators (6 (7)). On the surfaces of these gaskets (1 (2)) facing the separators (6 (7)), a gas lead-in groove (1 b) is formed extending such that manifold holes (1 a (2a)) provided in these gaskets (1 (2)) and a gas reaction area (10A) formed by the MEA (5) are communicated to each other. This gas lead-in groove (1 b) can be formed at the same time as the forming of the gaskets (1 (2)) by a rubber-like elastic material, and a gas lead-in groove need not be formed on the separator (6 (7)) side; therefore, costs can be reduced.
