Abstract
A resin injection molded article comprising at least a two-dimensional reinforcing core material formed into a non-planar shape, a resin surface layer covering the surface of the core material, and a resin-made structural member 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.

A method for fabricating a casing part of a portable electronic device, comprising:
- providing a reinforcing core material into a first mold;
- setting a second mold on a first surface of the core material, said second mold having a first hole for injecting a resin;
- injecting a resin from the first hole to construct a first resin surface layer covering the first surface of the core material;
- changing the first mold to a third mold and setting the third mold on a second surface of the core material which is different surface of the first surface, the third mold having a second hole for injecting a resin;
- and
- injecting a resin from the second hole to construct a second resin surface layer covering the second surface of the core material, the second resin surface layer being constructed integrally with the first resin surface layer on at least a part of the second resin surface layer.
