<P>PROBLEM TO BE SOLVED: To provide a polypropylene based resin composition being excellent in blocking-resistance, rigidity, impact-resistance at a low temperature, and odor. Ž<P>SOLUTION: The polypropylene based resin composition contains a polypropylene based copolymer containing 50-95 wt.% of a polymer component (component A) in which a structural unit derived from propylene is a main component, and 5-50 wt.% of a polymer component (component B) of propylene, ethylene and 4 or more C α-olefin in which a content (X) of a structural unit derived from propylene is 10≤X<50 wt.%, a content (Y) of a structural unit derived from ethylene is 50<Y≤70 wt.%, and a content (Z) of a structural unit derived from the 4 or more C α-olefine is 0<Z≤20 wt.% (provided that the total of X, Y and Z is made to 100 wt.%), and phosphites.
