Problem: It has been desired to form a plurality of combinations of plating films continuously on a single transfer rail and to form a plating film havi ng a high quality and a uniform thickness on the surfaces of a lead frame and leads. Solving Means: The plating apparatus is provided below the single transfer rail with a plurality of plating tanks, in which plating solution baths are disposed. By moving the plating solution between the plating tanks and the plating solution baths, it is possible to select a plating film to b e formed on a conductive member (21). As a result, it is possible to form combinations of plating films on the conductive member (21) continuously by the single transfer rail.
