A propylene-based resin composition produced by mixing the following components (A) and (B);

• (A) propylene-based resin composed of the following components (a1), (a2) and (a3):
• 90 to 40 wt. %
• (a1):
• propylene/ethylene block copolymer, composed of 60 to 83 wt. % of a crystalline propylene homopolymer component (a1-1 unit) and 17 to 40 wt. % of an ethylene/propylene random copolymer component (a1-2 unit) containing 30 to 52 wt. % of ethylene and having a weight-average molecular weight of 230,000 to 600,000;
• and having a melt flow rate (230° C., load:
• 2.16 kg) of 15 to 150 g/10 min. and number of gels of 100 or less for those having a size of 50 μm or more in a molded article of 25 cm2 (area) and 0.5 mm (thickness);
• 100 wt. parts,
• (a2):
• talc having an average particle size of 0.5 to 15 μm;
• 0 to 200 wt. parts.
• (a3):
• ethylene/α-olefin copolymer rubber, containing 20 to 50 wt. % of α-olefin of 3 to 8 carbon atoms and having a melt flow rate (230° C., load:
• 2.16 kg) of 0.3 to 100 g/10 min;
• 0 to 20 wt. parts, and
• (B):
• propylene-based resin material composed of the following components (b1) and (b2);
• 10 to 60 wt. %:
• (b1):
• propylene homopolymer or propylene/ethylene block copolymer, having a component insoluble in orthodichlorobenzene at below 120° C. accounting for 8 wt. % or more of the component insoluble at below 100° C., when fractionated with orthodichlorobenzene as the solvent, wherein the component insoluble at below 100° C. has a weight-average molecular weight of 200,000 or more and melt flow rate (230° C., load:
• 2.16 kg) of 0.3 to 70 g/10 min;
• 15 to 80 wt. parts, and
• (b2):
• talc or wollastonite having an average particle size of 0.5 to 15 μm;
• 20 to 85 wt. parts.
