    wherein
    1) the Mw/Mn value of xylene insolubles (XI) of the polypropylene composition as measured by GPC is in the range of 6 to 20,
    2) the weight ratio of component (1) to component (2) is in the range of 70:30 to 85:15,
    3) the intrinsic viscosity of xylene solubles (XSIV) of the polypropylene composition is in the range of 1.0 to 3.0 dl/g, and
    4) the MFR (at 230° C. under a load of 2.16 kg) of the polypropylene composition is in the range of 3 to 15 g/10 min.
