Polypropylene resin compositions are suited for injection molding and are capable of giving molded articles having excellent mechanical properties, reduced tendency to cause flow marks or weld marks, low gloss, and superior scratch resistance. A polypropylene resin composition includes: an amount of a resin composition (F) including a polypropylene (A), an ethylene-&#x3b1;-olef in copolymer or an ethylene-&#x3b1;-olefin-diene copolymer (B-I) having MFR of less than 0.4 g/10 min, an ethylene-&#x3b1;-olefin copolymer (B-2) having MFR of 0.5 to less than 20 g/10 min, and an inorganic filler (C); and specific amounts relative to the resin composition (F) of a modified polypropylene (D) and a surface modifier (E).
