A nucleating agent capable of simultaneously improving the thermal stability and transparency of a polyolefin resin, a polyolefin resin composition using the same, and a molded article thereof are provided. The following general formula (1) (In the general formula, R 1 to R 4 each independently represent a hydrogen atom, a linear or branched alkyl group having 1 to 9 carbon atoms, and R 5 is an alkanediyl group having 1 to 4 carbon atoms. And M represents a hydrogen atom or a sodium atom) in a nucleating agent containing a compound represented by), the mass ratio P/Na of a phosphorus atom and a sodium atom in the nucleating agent is in the range of 1.200 to 1.500. |
