Abstract: A method for producing a fuel cell separator capable of ensuring the working accuracy for a separator material. A surface of a mold is provided with grooves, each groove having a depth and width each equivalent to or larger than the thickness of a coating layer and equivalent to or smaller than the thickness of the separator material, the mold including an upper die having a projection/recess pressing surface on which projecting and recessed surfaces extending in a predetermined direction are alternately provided, and a lower die having a projection/recess pressing surface in a shape complementary to that of the pressing surface of the upper die.
