The process of forming a partial gold-plating pattern on a stainless substrate includes a first plating step, a second plating step, and a stripping step. In the first plating step, pretreatment is applied to a stainless substrate including opposite main planes and a processing site formed of a plane different from the main planes, after which a first gold-plating layer is formed all over the surface of the stainless substrate using a hydrochloric acid plating solution. In the second plating step, mask plating is used to form a second gold-plating layer on the first gold-plating layer that covers the processing site in a desired pattern, and in the stripping step, a portion of the first gold-plating layer in an area where there is none of the second gold-plating layer is stripped off using an alkaline stripping solution. |
