Zusammenfassung:An object of the present invention is to provide a polypropylene-based resin composition which is excellent in mechanical characteristics and molding processability, and is also capable of suppressing emission of a volatile organic compound. Disclosed is a polypropylene-based resin composition comprising a propylene-based block copolymer (A) which satisfies features (a), (b) and (c) shown below, and a zeolite (B) having a molar ratio SiO2/Al2O3 of 10 to 60 in an amount of 0.01 to 0.4 part by weight based on 100 parts by weight of the propylene-based block copolymer (A): Feature (a): the propylene-based block copolymer (A) is a propylene-based block copolymer containing a polymer component (I) and a polymer component (II); Feature (b): the polymer component (II) has a content of the units derived from at least one kind of comonomer selected from the group consisting of ethylene and α-olefins having 4 to 12 carbon atoms of from 1 to 80% by weight; and Feature (c): the propylene-based block copolymer (A) has a content of the polymer component (II) of from 5 to 70% by weight.
