Zusammenfassung:	To provide a method capable of satisfactorily reducing physical property variation of waste materials of a thermoplastic resin composition for a material of a thermoplastic resin product.SOLUTION: A method for manufacturing a thermoplastic resin composition according to the present invention includes the steps of: melting and kneading a recovery material containing foreign matter and a magnetic metal; removing the foreign matter using a mesh from the molten and kneaded recovery material; and removing the magnetic metal by use of a magnet from the molten and kneaded recovery material. The viscosity of the molten and kneaded recovery material before removing the foreign matter and the magnetic metal is greater than or equal to 50 Pa s and less than 1,000 Pa s.SELECTED DRAWING: Figure 1 【課題】熱可塑性樹脂製品の材料として熱可塑性樹脂組成物の廃材の物性のばらつきを十分に低減可能な方法を提供する。【解決手段】本発明における熱可塑性樹脂組成物の製造方法は、異物および磁性金属を含む回収材料を溶融混練する工程と、溶融混練された回収材料から、メッシュにより異物を除去する工程と、溶融混練された回収材料から、磁石により磁性金属を除去する工程とを含む。異物および磁性金属を除去する前の溶融混練された回収材料の粘度は、５０Ｐａ・ｓ以上、１０００Ｐａ・ｓ未満である。【選択図】図１
