ABSTRACT:
An automobile part comprising a polypropylene resin composition, the polypropylene resin composition comprising a propylene homopolymer (A1), an elastomer (B) and an inorganic filler (C) in specified proportions. The polypropylene homopolymer (A1) exhibits an MFR (230° C.) of 20 to 300 g/10 min, a ratio of position irregular units derived from 2,1-insertion or 1,3-insertion of propylene monomer relative to all propylene structural units, determined from a13C-NMR spectrum, each of 0.05% or less, and an Mw/Mn, determined by GPC, of 1 to 3.
