PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition improving impact resistance of a molded body obtained by injection molding or the like.SOLUTION: There is provided a polypropylene-based resin composition being the resin composition which is formed by adding 0.5 to 20 pts.wt. of carbon black to 100 pts.wt. of a polypropylene-based resin. In the polypropylene-based resin composition, a specific surface area of the carbon black is 20 to 100 m/g, and in a fine structure of the carbon black, an average particle size of the primary particles present in a single body or present while forming a structure by agglomerating a plurality of the primary particles, is 30 to 60 nm.SELECTED DRAWING: None |
