れ易い等の欠点がある。2. Description of the Related Art Conventionally, a porous metal is generally used for a positive or negative electrode substrate of a secondary battery or for various filters. A method is known in which a metal is electrodeposited by plating, and then the foamed resin is baked to eliminate the resin component of the foamed resin and sinter the deposited metal. There are drawbacks such as complicated processing and fragility of the skeleton of the porous metal.
