The invention provides resin molding. The purpose of the present invention is to provide a decorative resin molding which can be produced without complicating the production process while preventing increase of production costs and which can produce an effect such that observers can recognize decorative metallic patterns on the molding while appearance of the patterns change when the viewing angle or the lighting angle is changed and cannot be reproduced on the same metal plating surface. The resin molding includes an optically transparent plate-shaped portion, which has a smooth surface, and a convex surface having plural convex sections. The convex surface has a plurality of regions with widths. In each region width, a plurality of convex sections among which the ridge lines of every two adjacent convex sections face the same direction, wherein the direction is different from the angle directions of ridge lines of other regions, and at least one region is formed. A part of light entering from the smooth surface is totally reflected at the paired inclined surfaces of the convex sections. Total refection is formed at the smooth surface side forming the outer surface of the body of the molding, the appearance with metal colors is formed; the metal gloss changes with the viewing directions.
