つてもよい。 In the method of the present invention, a mask 5 corresponding to a pattern is provided on this entire gold-plated layer 4 (FIG. 1d). Masking in this case is performed by screen printing or coating with a photosensitive resist, taking into consideration the type of pattern and the shape of the surface of the material. Next, the gold plating layer 4 is removed by etching (FIG. 1e), and finally the mask 5 is peeled off (FIG. 1f) to obtain a variety of patterns. Although the drawing shows a case where the material is a flat surface, it may have a complex structure including inclined surfaces, curved surfaces, etc.
