PROBLEM TO BE SOLVED: To provide a polypropylene resin composition capable of providing a lightweight molded product having high strength and excellent resistance to surface peeling, especially a molded product suitable for a part for an automotive exterior material; and to provide the part for the automotive exterior material using the composition as a raw material. SOLUTION: The polypropylene resin composition contains (A) a crystalline polypropylene resin and (B) an acrylonitrile-styrene-based copolymer. The component (A) contains (A2) at least 1 wt.% modified polypropylene resin graft-modified with a copolymer of (a1) an ethylenic unsaturated bond-containing carboxylic acid or an anhydride thereof, and (a2) an aromatic vinyl compound, besides (A1) a crystalline polypropylene resin. The component (B) contains (B2) at least 1 wt.% epoxy-modified acrylonitrile-styrene-based copolymer besides (B1) an acrylonitrile-styrene-based copolymer. The part for the automotive exterior material comprises the composition. As a result, the polypropylene resin composition capable of providing the lightweight molded product having the high strength and the excellent resistance to the surface peeling, especially the molded product suitable for the part for the automotive exterior material, and the part for the automotive exterior material are provided.
