Abstract
A method for manufacturing a decorated-part comprises a first and second base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the first base coat-layer-forming process, the first base coat-layer colored in a highly light color at a lightness-level of 70 or more is formed on the surface of the resin base-material 12. In the second base coat-layer-forming process, the second base coat-layer 21C colored in a chromatic color is formed on the first base coat-layer. In the surface coat-layer-forming process, the surface coat-layer colored in a less-bright color at a lightness-level of 20 or less is formed on the second base coat-layer 21C. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the second base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.
