Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inorganic filler-reinforced polyolefinic resin composition having excellent rigidity, heat resistance, impact strength, moldability, weatherability and long-term heat resistance with hardly generating a glass fogging phenomenon. SOLUTION: This inorganic filler-reinforced polyolefinic resin composition is composed of following components A to E. (A): 95-50 wt.% of an ethylene.propylene block copolymer comprising a propylene homopolymer part having >=0.906 g/cm density and =45×10 Mw and =600 Mw and >=110 deg.C melting point in an amount of 0.1-5 pts.wt. to 100 pts.wt. of the component B, (D): an N-methyl type hindered amine-based stabilizer in an amount of 0.01-1 pt.wt. to total 100 pts.wt. of the components A and B, (E): a hindered phenolic antioxidant having >=110 deg.C melting point in an amount of 0.01-1 pt.wt. to total 100 pts.wt. of the components A and B.
