PURPOSE: To obtain a polypropylene resin composition having excellent low temperature impact resistance in addition to high rigidity, and excellent in the balance between the physical properties required as a raw material for industrial members. CONSTITUTION: A polypropylene resin composition comprises (A) 50-95wt.% of polypropylene, (B) 1-35wt.% of an ethylenic saturated triblock copolymer whose both terminal blocks have polyethylene structures and whose central block has an ethylene/α-olefin structure, and (C) 1-35wt.% of polypropylene oxide. Therein, the content of the polyethylene block in the component B is <=80wt.%, and the component B, the component C and the rubber component in the component A are contained in a total amount of 3-50wt.% based on the whole amount of the resin composition.
