Abstract: Provided are: a nucleating agent capable of imparting excellent mechanical properties to a molded article; a resin composition; a method of producing a resin composition; and a molded article. The nucleating agent contains: (A) an aromatic phosphate metal salt having a structure represented by Formula (1) (wherein, R1 to R5 each independently represent a hydrogen atom or an alkyl group; n represents 1 or 2; when n is 1, M1 represents an alkali metal or dihydroxyaluminum; and when n is 2, M1 represents an alkaline earth metal, zinc, or hydroxyaluminum); and (B) a carboxylic acid metal salt having a structure represented by Formula (2) (wherein, M2 represents an alkali metal, an alkaline earth metal, hydroxyaluminum, or dihydroxyaluminum; a represents 1 or 2; x represents 1 or 2; a and x satisfy ax=2; and Z represents a group having a structure represented by Formula (3) or (4)).

Abstract: Provided are: a nucleating agent composition capable of imparting excellent mechanical properties to a molded article containing a polyolefin-based resin; a resin composition containing the nucleating agent composition; the molded article having excellent mechanical properties; and a method for manufacturing the resin composition. The nucleating agent composition is characterized by containing at least one type of a nucleating agent for a polyolefin-based resin, wherein a β crystal fraction ranges from 0.2% to 71% as calculated by the following method. Through the use of a sample sampled from the pellets of the resin composition containing the nucleating agent composition, differential scanning calorimetry is performed according to a predetermined program to find a DSC curve, Q=f(θ), with the horizontal axis being temperature θ(° C.) and the vertical axis being heat flow rate Q(mW), and a baseline, g(θ), thereby obtaining a baseline-corrected DSC curve, Q′=h(θ)=f(θ)−g(θ). Subsequently, according to a predetermined procedure, a line area St and a β crystal area Sβ are found, thereby calculating the β crystal fraction (%).
