PURPOSE:To make the coating weight distribution uniform in the transverse direction of a steel strip by providing a dummy anode part which prohibits the passage of metallic ions to the top end on the plating face side of an anode basket in the axial direction thereof and supplying metallic particles for plating from the transverse direction above the lower limit level thereof. CONSTITUTION:An anode 4 is packed with the metallic particles 5 for plating in the anode basket 4d and the entire outside surface thereof is formed on a frame member 4b consisting of an insulating member. The effective anode part H constituted of a porous member 4a which allows the passage of the plating metallic ions and the dummy anode part G which is positioned above said part, is integrally formed on the frame member 4b and prohibits the passage of the plating metallic ions are constituted on the side to face the steel strip 1. Supply devices 20 for supplying the metallic particles 5 for plating into the anode basket 4 are successively provided to both ends of the dummy anode part G to supply the metallic particles 5 for plating from the transverse direction above the lower limit level of the dummy anode part G.
