Abstract
A resin product has a body made of a resin. The body has an outer surface including an ornamental surface and an unornamental surface, a first area defined on the outer surface, and a chemical plating layer and an electroplating layer respectively formed on the first area. A process for producing the resin product comprises the step of making a first boundary along a contour of the first area located on the ornamental surface, and the step of making a second boundary along a contour of the first area located on the unornamental surface. The step of making the second boundary includes forming a resist layer on the unornamental surface. The resist layer has a resistivity to a chemical plating solution for making the chemical plating layer. The process also includes the step of forming the chemical plating layer on the outer surface of the body except a part of the first boundary and the resist layer by chemical plating the body, and the step of selectively forming the electroplating layer on the chemical plating layer within the first area.
