摘要： An injection-molded product comprising: component A: 45 to 70% by weight of a propylene polymer 2.16 kg) of 10 to 100 g/10 min and an ethylene content of 0 to 15% by weight; and component B: 30 to 55% by weight of an ethylene/propylene copolymer-based rubber having a melt flow rate (at 230.degree. C. under a load of 5 kg) of 0.5 to 20 g/10 min and a propylene content of 20 to 40% by weight; the ratio MFR.sub.A /MFR.sub.B of the melt flow rate (MFR.sub.A) of component A to the melt flow rate (MFR.sub.B) of component B being 0.5 to 50, and the molded product having such physical properties as expressed in terms of a modulus in flexure of 2,000 to 5,000 kg/cm.sup.2, as determined according to JIS-K7203 and a coefficient of linear expansion of 10 .times.10.sup.-5 /.degree. C. or below, as determined according to ASTM-D696, and having an average thickness of 2 to 7 mm.
