Disclosed is a thermoplastic resin composition comprising specific amounts of (A) a polypropylene resin, (B) an elastomer, (C) inorganic filler, (D) a resin having a melt tension of 0.1 N or more and a swelling ratio of 1.8 or more and being characterized by that the time required for the resin until the ratio (G(t)/G(0.02)) of a relaxation modulus G(t) measured at 210° C. to a relaxation modulus G(0.02) at a time of 0.02 sec reaches 0.01 is 10 sec or more, and (E) a resin characterized by that, with respect to a swelling ratio measured at 220° C. at an L/D of an orifice of 40, the ratio of a swelling ratio (SR10<3>) at a shear rate of 2.4x10<3 >sec<-1 >to a swelling ratio. (SR10<2>) at a shear rate of 1.2x10<2 >sec<-1>, SR10<3>/SR10<2>, is from 1.0 to 1.1.
