This invention is to provide a mold for a fuel cell separator with which a flash, even if it occurs, does not cause a thickness unevenness. A mold for producing a fuel cell separator, comprising a plurality of mol ds 2, 4 and 10, and a fuel cell molding cavity for separator 5 being defined among the molds, wherein at least one of the molds is provided with a flash reservoir cavity 11 which is communicated with the cavity 5. An amount of material in excess of the volume of the cavity 5 is charged, and melted by the applicati on of pressure and heat. The melted material fills up the entire cavity 5, with the excess thereof entering the cavity 11. Since the molds 2 and 10 maintain a direct contact with each other, it is possible to obtain a separator molde d with a high accuracy.
