After completion of the copper sulfate plating step, washing with water is performed, and further washing with pure water is performed. After this, the material 2 to be plated is removed from the jig 1 and the thickness of the plating film is measured. Then, the jig 1 is again mounted on the jig 1 for acid degreasing and further washed with water. After this water washing step, the electrolytic copper plating step is entered through a soft etching step, a water washing step, a pure water washing step, and an acid washing step. After this plating is completed, the electrolytic nickel plating process is performed through each of the water washing, pure water cleaning, and acid cleaning processes. After the plating is completed, the electrolytic gold plating is performed. Then, the material to be plated 2 is removed, and all the steps of electrolytic plating are completed through the steps of hot water washing and nitrogen drying. Here, in the present embodiment, the plating material 2 remains attached to the jig 1 in the steps other than the film thickness measurement, but when the plating material 2 is removed from the jig 1 for film thickness measurement. Since the material to be plated 2 only needs to be slid upward in the grooves 102, 102, the removal work can be easily performed, and the remounting work can be easily performed, so that productivity is improved.
