Abstract: A propylene resin composition comprising: 100 parts by mass of a heterophasic propylene polymer material (A) comprising a propylene polymer (I) and an ethylene-?-olefin copolymer (II); 0.1 to 5 parts by mass of an organo-modified siloxane compound (B) having a weight-average molecular weight of 10,000 to 90,000; and 0.001 parts by mass to 5 parts by mass of a colorant (C). The propylene polymer (I) is a propylene homopolymer (I-1) or a propylene copolymer (I-2). The propylene copolymer (I-2): a copolymer comprising a structural unit derived from propylene and a structural unit derived from at least one olefin selected from the group consisting of ethylene and ?-olefins having 4 to 12 carbon atoms, where an amount of the structural unit derived from at least one olefin selected from the group consisting of ethylene and ?-olefins having 4 to 12 carbon atoms is 0.05 mass % or more and less than 10 mass %.
