PROBLEM TO BE SOLVED: To provide a propylene resin composition which simultaneously satisfies excellent impact resistance and moldability, and is suitably used for automobile interior and exterior parts although the use proportion of rubbers and elastomers is reduced; and to provide a method for producing the same, and a molded product for automobile parts.SOLUTION: The propylene resin composition contains (A) 57 to 87 mass% of a propylene block copolymer composition having a melt flow rate (temperature: 230°C, load: 21.18 N) of 10 to 70 g/10-min, (B) 2 to 10 mass% of an ethylene-octene copolymer having a 1-octene content of 10 to 60 mass%, (C) 1 to 5 mass% of a polystyrene-ethylene-butylene-polystyrene triblock copolymer having a styrene content of 10 to 40 mass%, (D) 9.5 to 25 mass% of a talc having an average particle diameter of ≤5 μm, and (E) ≥0.5 and <3 mass% of calcium carbonate having an average particle diameter of ≤1.5 μm. |
