The present invention provides A polypropylene-based resin composition, comprising (A) 45 to 85 wt. % of a propylene/ethylene block copolymer, having a melt flow rate (MFR) of 100 g/10 min. or more for the propylene homopolymer portion and 50 to 200 g/10 min. for the total copolymer, (B) 0.5 to 20 wt. % of a propylene homopolymer having a weight-average molecular weight (Mw) of 10,000 to 110,000, (C) 5 to 35 wt. % of an ethylene/alpha-olefin copolymer rubber and/or ethylene/alpha-olefin/non-conjugate diene copolymer rubber, and/or hydrogenated block copolymer rubber, having an MFR of 0.1 to 20 g/10 min., and (D) 5 to 30 wt. % of talc having an average particle size of 10 mum or less, determined by the laser diffraction method.
