Abstract
Disclosed are a polypropylene-based resin composition comprising 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 part of 6% by mass or more, 0 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) which is a random copolymer composed of ethylene and an α-olefin having 4 to 8 carbon atoms, and has a density of 0.850 to 0.890 g/cmand an MFR of 0.5 to 30 g/10 min, and 30 to 40 parts by mass of an inorganic filler (D) having an average particle size of over 3.0 μm and less than 5.0 μm [the total amount of the components (A) to (D) is 100 parts by mass]; and an automobile exterior member obtained by injection-molding or press-molding the composition.
