Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a molded article excellent in impact resistance comprising mixing a polypropylene resin, an ethylene copolymer rubber and an inorganic filler-containing polypropylene resin and subjecting the resulting mixture to injection molding or extrusion. SOLUTION: The method for producing the molded article comprises mixing an inorganic filler-containing polypropylene resin which contains the inorganic filler in an amount of 20-300 pts.wt. per 100 pts.wt. of the polypropylene resin, a polypropylene resin and an ethylene copolymer rubber in the presence of a polyalkylene glycol in an amount of 0.1-2 pts.wt. per 100 pts.wt. of the sum of the inorganic filler, the polypropylene resin and the ethylene copolymer rubber and subjecting the resulting mixture to injection molding or extrusion.
