Summary:PROBLEM TO BE SOLVED: To provide a separator for a solid polymer fuel cell having high corrosion resistance and a low contact electric resistance.SOLUTION: The separator for a solid polymer fuel cell has a cermet layer consisting of a metallic bond phase containing Cr, and hard phase particles containing a boride and/or a carbide on a base metal. A passive film containing Cr as a main component is formed at least partially on the outermost layer of the cermet layer.
