<P>PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition excellent in balance of slip characteristics, stiffness, and impact resistance at a low temperature, moreover excellent in odor. Ž<P>SOLUTION: The polypropylene-based resin composition includes a polypropylene-based copolymer and a nucleating agent, wherein the polypropylene-based copolymer comprises a 50-95 wt.% polymer component (component A) whose main component is comprised of a structural unit originated in propylene, and a 5-50 wt.% polymer component (component B) comprised of propylene, ethylene, and an α-olefine whose carbon number is 4 or more, wherein, content (X) of a structural unit originated in propylene is 10≤X<50 wt.%, content (Y) of a structural unit originated in ethylene is 50<Y≤70 wt.%, and content (Z) of a structural unit originated in the α-olefine whose carbon number is 4 or more is 0<Z≤20 wt.%.
