摘要： A metallic separator for a fuel cell (and a manufacturing method therefore) can reduce damage to an electrode assembly, open up the maximum capacity of the reducing effect of contact resistance due to coating of gold by gold plating or the like, and reduce consumption of gold to lower the cost. Conductive inclusions are exposed at the surface with corrosion resistance, and at least one kind of metal or an alloy thereof selected from silver, copper, nickel, and tin is precipitated on the exposed conductive inclusions. From the viewpoint of reducing contact resistance, the conductive inclusions preferably protrude from the separator surface.
