PROBLEM TO BE SOLVED: To obtain the subject composition for automobile parts, etc., having improving effects for stable productivity, quality stability and productivity by compounding a specific polypropylene resin with a specific elastomer and a specific talc. SOLUTION: This thermoplastic resin composition comprises (A) 30-85 wt.% polypropylene resin, (B) 5-40 wt.% granule-type elastomer having 60-80 JIS-A hardness, 1,000 to 2,000μm weight-average particle diameter and 0.10-0.30 g/cc bulk density and (C) 10-40 wt.% talc having 1-5μm weight average particle diameter. Furthermore, a propylene-ethylene copolymer, etc., synthesized by multistage polymerization is preferably used as the component A and ethylene- propylene copolymer, etc., is preferably used as the component B.
