PURPOSE:To produce an electrode for plating without causing positioning by lead during work by adhering and joining a rolled lead or lead alloy plate to the electric discharge surface, exclusive of a current receiving connecting part, of a base material made of a metal by diffusion welding in vacuum or in an inert gaseous atmosphere. CONSTITUTION:A lead or lead alloy plate, a rolled lead or lead alloy plate 4 is adhered and joined to the whole or only the necessary part of the electric discharge surface 3, exclusive of a current receiving connecting part 2, of a base material 1 made of a metal such as iron by diffusion welding in vacuum or in an inert gaseous atmosphere to tightly bind and produce an electrode for plating.
