摘要： A polypropylene-based resin composition containing: 5 to 47 parts by mass of a propylene-based polymer (A) having an MFR of 50 to 150 g/10 min and an amount of a decane-soluble portion of 6 to 15% by mass, 20 to 30 parts by mass of a propylene homopolymer (B) having an MFR of 10 to 500 g/10 min, 23 to 30 parts by mass of an ethylene/α-olefin copolymer (C) being a random copolymer of ethylene and an α-olefin having 4 to 8 carbon atoms, and having a density of 0.850 to 0.880 g/cm 3 , an MFR of 0.5 to 30 g/10 min, and a melting point peak of 110°C or more, and 30 to 40 parts by mass of an inorganic filler (D), provided that a total amount of the components (A) to (D) is 100 parts by mass.
