To provide a polypropylene-based resin composition which is excellent in flowability and can give molded products excellent in appearances, and to provide a foamed molded product comprising the same.

This polypropylene-based resin composition comprises 100 pts.wt. [the total amount of (A) and (B) is 100 wt.%] of a resin composition comprising 40 to 99 wt.% of at least one propylene polymer (A) selected from the group consisting of propylene homopolymer (A-1) and the following propylene-ethylene block copolymer (A-2), and 1 to 60 wt.% of the following ethylene--olefin copolymer (B), and 0.1 to 20 pts.wt. of a petroleum resin (C). (A-2) The propylene-ethylene block copolymer in which []EP of the propylene-ethylene block copolymer component is 2 to 8 (dl/g), and (B) the ethylene--olefin copolymer in which the carbon atom number of the -olefin is 4 to 20, and MI (190C) is 1 to 40 g/10 min.
