ABSTRACT:
Process of imparting conductivity to a three-dimensional net-shaped porous sheet can be performed efficiently before carrying out electroplating process. Fine metallic powders are applied to the porous sheet made of a foamed sheet, a nonwoven sheet, a mesh sheet or a plurality of sheets layered one on the other, so that a conductive metallic layer is formed on the porous sheet. Then, an electroplated layer is formed on the surface of the conductive metallic layer. The conductive metallic layer remains when the porous sheet burned out. Consequently, a metallic layer of the conductive metallic layer and the electroplated layer forms the metallic framework of the metallic porous sheet.
