A press separator made of a stainless steel sheet, for providing excellent corrosion resistance and electric conductivity by a combination of a passive coating and a deposition of a boride or a boron carbide, restricting corrosi on without separation nor coming-off, by press forming, of depositions, and ensuring an extended service. A stainless steel sheet, containing 0.005-1.5 wt.% of B and having deposited on the surface thereof at least one kind out of M23(C, B)6 type boron carbide, and M2B type and MB type borides, is press- formed in a corrugated shape having continuous irregularities, with angles o f bent portions formed by bending or unbending by press forming being set at a t least 15 degrees and an outward bending r-value at up to 1 mm. |
