Abstract
A separator includes a gas flow path forming body, which includes a substrate made of stainless steel, a resin layer arranged on the substrate, and a conductive layer arranged on the surface of the resin layer. The resin layer contains a filler, which has conductivity and greater hardness than an oxide film of the substrate. The conductive layer contains graphite. The filler extends through the oxide film of the substrate and contacts the base material.
