Disclosed is a polypropylene resin composition including from 50 to 94% by weight of polypropylene resin, from 1 to 25% by weight of ethylene-.alpha.-olefin copolymer rubber including ethylene units and units of C.sub.4-12 .alpha.-olefin, the copolymer having a density of 0.850-0.870 g/cm.sup.3 and an MFR of 0.05-1 g/10 min, and from 5 to 25% by weight of inorganic filler, wherein the polypropylene resin is a propylene-ethylene block copolymer satisfying given requirements or a polymer mixture of the propylene-ethylene block copolymer and a propylene homopolymer. Molded articles made from the composition have good balance between rigidity and impact resistance and have good appearance.
