A method and an apparatus for producing a microporous metal foil by forming fine pores in a metal foil passing through a gap between a pattern roll having high-hardness fine particles on the surface and a hard metal roll; (a) a plastic sheet laminate comprising a soft plastic layer and a hard plastic layer having high tensile strength being interposed between the metal foil and the hard metal roll, with the soft plastic layer on the metal foil side; and (b) mechanical vibration being given to at least one of the pattern roll and the hard metal roll. |
