PURPOSE:To prevent falling-off of an active material from an electrode substratum and to prevent cracking and collapsing of a cylindrical electrode by applying metal plating on a foamed layer of a synthetic resin adhered to a multiperforated conductive thin plate. CONSTITUTION:A foamed resin, such as polyurethane or polystyrene, is bonded by adhesion or fusion on a multi-perforated metallic plate, such as a screen, a perforated plate or an expanded metal plate. The foamed resin layer is then subjected to electrolytic plating after electroless plating, washing, drying and heat treatment to remove the foamed resin layer, thus producing an electrode substratum consisting of a cored foamed metal. |
