摘要

An Au plating film (12) is formed on the surface of a plate-shaped metal bas e (13) made of a metal more base than Au, and the metal base is cut along a li ne of cutting plane (18) reflecting the visible outlines of a member to form a separator (10). The thus formed separator (10) has an Au plating film (12) o n a major surface (10a) and a cut face (16), which is an edge face (16) continuous with the major surface (10a). A part of the metal base (13) is exposed from a part of the cut face (16). The width of the exposed part is 1 mm or less. In such a way, a metal member for fuel cells having a sufficient corrosion resistance and producible readily at low cost, its manufacturing method, and a fuel cell having such a metal member for fuel cells are provid ed.
