Zusammenfassung:	PURPOSE:To provide the title composition excellent in rigidity, low-temperature impact resistance, etc., by mixing a specified propylene/ethylene block copolymer with an ethylene/propylene/butene-1 copolymer rubber and a filler in a specified weight ratio. CONSTITUTION:A filler-reinforced propylene resin composition is produced by mixing 30-94wt.% amorphous propylene/ethylene block copolymer of an ethylene content of 2-20wt.%, a room temperature xylene-soluble content of 3-35wt.% and an MFR of 2-100g/10min with 35-1wt.% ethylene/propylene/butene-1 copolymer rubber of a propylene content and a butene-1 content of 20-55wt.% and 3-15wt.%, respectively, and having an MFR (at 230 deg.C under a load of 2.16kg) of 0.5-25g/10min and a degree of crystallization
