摘要： An Au plated film 12 is formed on the surface of a plate-formed metal base 13 composed of a metal less noble than Au, and the product is cut along a planned cutting line 18 reflecting a contour of a desired component, to thereby form a separator 10. Thus-formed separator 10 has the Au plated film 12 formed on the main surface 10a thereof, and has a cutting plane 16 formed as an end face 16 stretched up to the main surface 10a. The metal base 13 exposes in a part of the cutting plane 16, in a width of the exposed region of 1 mm or less. This is successful in providing a metal component for fuel cell which is satisfactory in the corrosion resistance and allows easy fabrication at low costs, a method of manufacturing the same, and also in providing a fuel cell having thus-fabricated metal component for fuel cell.
