PURPOSE:To prevent damage of a plating mask, etc., and also to suppress a defect of plating to the minimum by punching a terminal part and an initial part of plural pieces of strip materials, to uneven shapes, respectively, connecting them by fitting them as one body, and supplying it continuously to a plating line. CONSTITUTION:A terminal part and an initial part to be connected to each other, of plural pieces of strip materials which have been cut to a prescribed length are punched to uneven shapes which are engaged to each other, respectively. A recessed type terminal part 2 and a projecting type initial part 2' which have been formed and pressed in this way are fitted to each other as one body, and a gap of the fitting part is welded thermally by a brazing filler material 3. As a result, a connecting part whose plate thickness does not increase is formed, and plating is executed by supplying continuously the connected strip material to a plating line. In this way, no plate thickness increases in the connecting part, damage of a mask part is not generated, also bleeding of plating in the connecting part is suppressed to the minimum, and the yield of a plating work is improved.
