摘要

PROBLEM TO BE SOLVED: To manufacture a resin molded product having exterior display parts regardless of a distance between adjacent exterior display parts and sizes of the exterior display parts. SOLUTION: A light transmissive resin layer 120 having a concave part 121 on its back face is molded by injection molding of light transmissive resin by using a predetermined die. Next, light-shielding resin is poured into the predetermined die so as to fill at least the concave part 121 with the light shielding resin for injection-molding a light-shielding resin layer 160 which is a layer made of the light-shielding resin on the back face of the light transmissive resin layer 120. After injection-molding the light-shielding resin layer 160, the light-shielding resin layer 160 other than a light-shielding resin part 130 or the light transmissive resin layer 120 is cut, which produces the resin molded product having the exterior display parts 110.
