Abstract
A method for producing a porous metal foil comprising causing a metal foil together with a soft sheet to pass through a gap between a pattern roll of a hard metal, which has high-hardness, fine particles having particle sizes of 50-500 μm on the surface, and a hard metal roll opposing the pattern roll, to press the metal foil and the soft sheet, thereby forming fine pores in the metal foil; the soft sheet being a laminate sheet of a relatively hard plastic layer and a relatively soft plastic layer; and the pressing of the metal foil being conducted with the relatively hard plastic layer on the side of the metal foil, and the relatively soft plastic layer on the side of the hard metal roll.
