PROBLEM TO BE SOLVED: To provide a polyolefin resin composition having a sufficient stabilizing effect and excellent cost performance. SOLUTION: The polyolefin resin composition contains a polyolefin resin, to which a phenol antioxidant represented by general formula (I) (wherein, R represents a 1-30C alkyl group, etc., which may have a branch and/or a cycloalkyl group) has been masked with an organic aluminum compound, and a phosphorous antioxidant, are added to a catalyst system or a polymerization system prior to or during polymerization of an olefin monomer and polymerized; wherein 0.001-0.5 pts.mass of the phenol antioxidant represented by the general formula (I) and 0.001-3 pts.mass of the phosphorous antioxidant are added with respect to 100 pts.mass of the olefin monomer.
