Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject composition capable of producing a molding product having excellent balance of rigidity and impact resistance (especially low-temperature impact resistance) by including a specific block copolymer, glass fibers and a prescribed polypropylene. SOLUTION: This composition is obtained by compounding (A) 40-98 wt.% of a propylene block copolymer which comprises (i) a polymer block composed of a propylene homopolymer or a random copolymer of (a) propylene and (b)
