摘要

The present invention is capable of further reducing the weight and improving the surface quality in the thin-wall molding of electrical components such as mobile phones and personal computer housings, and automobile components such as automobile fenders, door panels, back door panels, garnishes, pillars, and spoilers. And it aims at providing the molded object which can design a rib. The injection foam molded article of the present invention is an injection of a resin composition containing (A) a polycarbonate resin, (B) a thermoplastic polyester resin, (C) a polyester-polyether copolymer, and (D) a foaming agent. It is a foam molded article, and the surface roughness is 0.1 μm
