Resin article having plating layer and manufacturing method thereof

Abstract

There is provided with a method for manufacturing a resin article having a plating layer, obtained by forming a plating layer on a portion of the surface of a resin article. The surface of the resin article is treated with a mask material solution. A portion of the surface of the resin article is irradiated selectively with ultraviolet rays such that it is possible to apply an electroless plating catalyst to the portion of the surface of the resin article. An electroless plating catalyst is applied to the portion of the surface of the resin article irradiated with ultraviolet rays. A plating layer is formed on the portion of the surface of the resin article irradiated with ultraviolet rays, using electroless plating.
