Abstract
A polypropylene-based resin composition capable of affording a molded article superior in tensile elongation at break includes a polypropylene resin (A), an ethylene-α-olefin copolymer (B) having a density of 0.865 to 0.890 g/cm, an ethylene-α-olefin copolymer (C) having a density of 0.855 to 0.859 g/cm, and an inorganic filler (D), wherein the content of the polypropylene resin (A) is 49 to 76% by weight, the content of the inorganic filler (D) is 9 to 22% by weight, the sum total of the contents of the ethylene-α-olefin copolymer (B) and the ethylene-α-olefin copolymer (C) is 15 to 29% by weight. The sum total of the contents of (A), (B), (C), and (D) is taken as 100% by weight, and the content of the ethylene-α-olefin copolymer (B), x % by weight, and the content of the ethylene-α-olefin copolymer (C), y % by weight, satisfy the formula: 0.07≤x/(x+y)≤0.41.
