C. under a load of 2.16 kg and containing components extractable with xylene at 20.degree. C., wherein the xylene-extractable components having an intrinsic viscosity as measured at 140.degree. C. in decalin of from 2.0 to 5.0 g/dl; (B) an ethylene/propylene rubber having a propylene content of from 40 to 60% by weight and a melt flow rate of from 0.5 to 10 g/10 min as measured at 230.degree. C. under a load of 2.16 kg; (C) a triblock copolymer having a melt flow rate of from more than 40 to 200 g/10 min as measured at 230.degree. C. under a load of 2.16 kg, a flat interface between said triblock copolymer and the 100.degree. C. xylene-insoluble components of said polypropylene polymer of ingredient (A) having a critical energy release rate of 20 J/m.sup.2 or higher as measured at a phase angle of from -2.degree. to -12.degree.; (D) a modified polyolefin polymer having a hydroxy group, said modified polyolefin polymer having a content of a hydroxy-containing unsaturated compound of from 0.5 to 7.0% by weight; (E) an oligomer having at least one terminal polar group, said oligomer having a number-average molecular weight of from 300 to 10,000; and (F) talc having an average particle diameter of 5 .mu.m or smaller.
