The present invention provides a nucleating agent capable of simultaneously improving thermal stability and transparency of a polyolefin resin, a polyolefin-based resin composition using the same, and a molded article thereof. Contains 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 represents 1 carbon atom. In the alkanediyl group of ~ 4, M represents a hydrogen atom or a sodium atom) In the nucleating agent of the compound represented by M, the mass ratio P / Na of the phosphorus atom and the sodium atom in the nucleating agent is in the range of 1.200 to 1.500. |
