A polypropylene-based resin composition contains: a component (A1) being a propylene homopolymer or a copolymer of propylene and a 30 wt % or less -olefin having 2 or 4 to 8 carbon atoms, having a intrinsic viscosity of more than 20 dl/g, as measured in a tetralin solvent at 135 C.; and a component (A2) being a polymer selected from the group consisting of (A2-1) a propylene homopolymer, (A2-2) a random copolymer of propylene and an -olefin having 2 or 4 to 8 carbon atoms, (A2-3) a block copolymer of propylene and an -olefin having 2 or 4 to 8 carbon atoms, and a combination of the (A2-1), (A2-2), and (A2-3). The resin composition has a content of the component (A1) of 0.1 to 10 wt % and a content of the component (A2) of 99.9 to 90 wt % based on the total amount of the component (A1) and the component (A2). The component (A2) has a melt flow rate (MFR) (230 C., load: 2.16 kg) of 1 to 500 g/10 min.
