Abstract
This method is for producing a compact (fuel-cell separator) having a projection by pressing a plate by a die and a punch. A tip end surface of the punch presses the plate to form an overhang, and then a sidewall of the overhang is sandwiched between an inclined surface of the die and an inclined surface of the punch, and in this state the sidewall is rolled, thereby forming the projection.
