In a plating method for mounting a tubular workpiece having openings at both ends in an axial direction thereof on a power feeding clip and immersing the tubular workpiece in a circulated plating solution to plate the tubular workpiece, the mounting of the tubular workpiece on the power feeding clip is performed by inserting the power feeding clip into the tubular workpiece from one of the openings of the tubular workpiece. The power feeding clip is configured by a folded metal plate, and includes a plurality of elastic contact pieces that can elastically contact the inner surface of the tubular workpiece to hold the tubular workpiece and supply power to the tubular workpiece, and a restraining part that is located inside the tubular workpiece and restrains flow of the plating solution in the axial direction.
