[Solution] A polypropylene-based resin composition comprising (C) 0.2 to 1 parts by weight of a fatty acid amide and (D) 0.2 to 1 parts by weight of a surfactant with respect to 100 parts by weight of a substrate component formed from: (A) a polypropylene-based resin having an MFR of 10 to 300g/10min, and including a propylene-based polymer in the amount of 98mol% or more in structural units derived from propylene; (B) an ethylene/[alpha]-olefin copolymer containing ethylene in the amount of 65 to 90mol%; and, as necessary, (E) an inorganic filler. [Effect] According to the present invention, it is possible to provide a polypropylene-based resin composition which has excellent moldability, including injection moldability, rigidity and impact resistance, and with which it is possible to effectively suppress surface texture deterioration caused by friction with flexible objects such as rubber-like objects (resistance to scratching from kicking), and to manufacture a compact suitable for use in automotive interior and exterior parts.
