A conductive material suitable as a gasket material for shielding the electromagnetic wave and a method of fabrication thereof are disclosed. The conductive material is intended to protect electronics equipment and devices from an erroneous operation which otherwise might be triggered by the electromagnetic wave leaking from other electronic equipment or devices and also to prevent a radio wave interference with communication equipment. A composite material sheet composed of a synthetic fiber-structured sheet and a porous synthetic resin sheet integrally bonded to each other is plated with a metal. In order to improve the working efficiency for final applications, an adhesive layer covered with the releasing paper is formed on one of the sheet surfaces.

Conductive material and its manufacture thereof

A material for clothes is disclosed which is formed of a base cloth and a porous film having a number of very fine pores and coated on at least one surface of the base cloth. In this case, the pores are made to have a diameter about 0.1 to 5 .mu.m and the material has the percentage of dust permeation less than 50% for the dust with size larger than 0.3 .mu.m and moisture permeability more than 2500 g/m.sup.2 /24 hrs.
