[Solution] A polypropylene resin composition includes 100 parts by weight of basic components including a polypropylene resin (A) including a propylene polymer, the propylene polymer having a MFR of 10 to 300 g/10 min and containing 98 mol % or more of structural units derived from propylene, an ethylene.α-olefin copolymer (B) having an ethylene content of 65 to 90 mol %, and optionally an inorganic filler (E); 0.2 to 1 part by weight of a fatty acid amide (C); and 0.2 to 1 part by weight of a surfactant (D). [Effect] The polypropylene resin compositions of the invention have excellent shaping properties such as injection molding properties and can give shaped articles which exhibit excellent properties such as rigidity and impact resistance and which are effectively prevented from deteriorations in surface properties due to friction with soft substances such as rubbers (namely, have excellent kicking scuff resistance), thus finding suitable applications in automobile interior and exterior parts.
