Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a material-recycled cellular phone housing made in thin wall and reduced weight so as to contribute to the reduction of global environmental load.SOLUTION: This material-recycled cellular phone housing is obtained by molding a composite polylactic acid-based thermoplastic resin composition (II) including a recovered resin component recovered from cellular phone housings composed of a composite polylactic acid-based thermoplastic resin composition (I). The recovered resin component is a sorted product sorted by an optical discrimination device after respective steps of disassembling and crushing. The compositions (I) and (II) each contains a polylactic acid resin (A), a rubber-containing styrene-based resin (B) and a polyethylene naphthalate fiber (C), where the content of recovered resin component in the composition (II) is 1-50 pts.wt. based on 100 pts.wt. in total of components (A) to (C) in the composition (II).
