A separator of this invention is so constructed that a plurality of protrusions are implanted in a substrate which forms a reactive chamber of a fuel cell. The substrate has a multiple layered structure in which a single side or both sides of a mesh foundation are covered with resin layer and contains through holes at positions corresponding to each of the protrusions. Each of the protrusions is formed by allowing black lead ink applied on the single side or both sides of the substrate to invade each through hole. Consequently, the substrate can be formed to be super thin, lightweight and the respective protrusions can be easily formed at low cost.
