Abstract: Provided are a resin composition that is capable of imparting excellent mechanical strength to a molded article and has excellent dimensional stability during molding, a molded article thereof, and a method for producing the resin composition. For a resin composition containing a polyolefin-based resin and a nucleating agent, a ratio t2/t1 between an isothermal crystallization time t2 at 135° C. of the resin composition and an isothermal crystallization time t1 at 135° C. of a nucleating agent-free resin composition having the same formulation as the resin composition except that the nucleating agent is not contained is 0.45 or more.

Abstract: Provided are: a polyolefin resin composition that is unlikely to be affected by an NOx gas; and a molded article using the same. The polyolefin resin composition includes, with respect to 100 parts by mass of a polyolefin resin (A): 0.001 to 5 parts by mass of a hindered amine compound (B) which has a nitrogen content of less than 4.0% by mass and a molecular weight of 500 or less; and 0.001 to 5 parts by mass of a phenolic antioxidant (C). The hindered amine compound (B) which has a nitrogen content of less than 4.0% by mass and a molecular weight of 500 or less preferably contains a compound represented by the following Formula (1), where R1 represents a hydrogen atom or a methyl group; and R2 represents a linear or branched alkyl group having 1 to 22 carbon atoms:
