Abstract

Abstract A resin injection molded article comprising at least a two-dimensional reinforcing core material (11) formed into a non-planar shape, a resin surface (20) layer covering the surface of the core material, and a resin-made structural member (19) formed integrally with the resin surface layer and protruding from the resin surface layer, wherein the resin surface layer and the structural member are integrally molded by injection molding. The two-dimensional core material may be used as a design. <IMAGE>
