PROBLEM TO BE SOLVED: To provide a separator for a fuel cell preventing the generation of the peeling off or the crack of a gold covering layer after plastic working and remarkably enhancing corrosion resistance and durability. SOLUTION: In the separator for the fuel cell in which the gold covering is formed on the surface of a metal plate, when the minimum bending R in a plastic working part is represented by r (μm) and the thickness of the gold covering layer is by d (μm), the relation of (r+d)/r<=1.025 (wherein, 50 μm<=r<=1000 μm) is satisfied. |
