<P>PROBLEM TO BE SOLVED: To provide a resin molding in which a weld line is made inconspicuous. <P>SOLUTION: The manufacturing method of the resin molding includes: a preparation step of preparing a coloring material and a light transmission material having a viscosity lower than that of the coloring material in a molten state and light transmittance higher than that of the coloring material; a filling step of filling the coloring material and the light transmission material in the molten state into a mold; and a solidifying step of solidifying the filled coloring material and the light transmission material. The resin molding 1 is provided with a metallic layer 3 formed from the coloring material and a clear layer 4 provided on the surface side rather than the metallic layer 3, formed from a light transmission material having light transmittance higher that of the coloring material and simultaneously molded with the metallic layer 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
