The object of the invention is to provide a separator of high strength plus high corrosion resistance which makes it possible to easily fabricate a polymer electrolyte type fuel cell having an extremely limited contact resistance with unit cells of an increased effective area, and a process for the fabrication of such separators. The invention provides a polymer electrolyte type fuel cell that comprises a metal substrate having a groove formed in at least one surface, an electrically conductive resin layer formed by electrodeposition in such a way as to cover the metal substrate, and a gas diffusion layer located on the surface of said metal substrate having a groove. Such a separator is fabricated by forming a groove in at least one surface of a metal sheet material to make a metal substrate; forming an electrically conductive coating film in such a way as to cover the metal substrate, using an electrically conductive electrodeposition solution; and engaging and placing a gas diffusion layer on the resin coating film except the groove in such a way as to veil the groove in the metal substrate, and thereafter curing the resin coating film to form a resin layer while joining the gas diffusion layer to the metal substrate to form a feed groove surrounded with the groove and the gas diffusion layer.
