Abstract: The present invention provides a method capable of producing an olefin resin composition for a home electric appliance materials and automotive interior materials that has good color tone and shows excellent fogging resistance, in which method the total amount of stabilizer(s) to be added is reduced and cost reduction can thus be attained. The method of producing an olefin resin composition for an automotive interior material by polymerization of an olefin monomer according to the present invention is characterized by comprising the step of adding, before or during the polymerization of an olefin monomer, 0.001 to 0.5 parts by mass of a phenolic antioxidant, which is represented by the following Formula (1) and masked with an organoaluminum compound, with respect to 100 parts by mass of an olefin resin obtained by the polymerization: (wherein, R represents an alkyl group having 1 to 30 carbon atoms which is optionally branched, a cycloalkyl group having 3 to 12 carbon atoms which is optionally substituted or an aryl group having 6 to 18 carbon atoms which is optionally substituted).
