PROBLEM TO BE SOLVED: To provide a master batch composition useful for producing the injection molded articles of a polyolefin-based composition, especially a polypropylene-based resin, especially a master batch composition which can improve the dispersibility of additives in polyolefin molded articles, makes possible to highly charge various kinds of additives in the master batch composition, to provide a polyolefin-based resin composition containing the composition, and to provide a polyolefin molded article using the resin composition. SOLUTION: This master batch composition comprises 10 to 95 mass% of an additive for plastics, 1 to 50 mass% of an olefinic polymer having specific physical values, and 1 to 89 mass% of a polyolefin resin for carrier. The polyolefin-based resin composition prepared by compounding a polyolefin-based resin with the master batch composition. The polyolefin molded article prepared by molding the composition.
