The present invention is excellent in dispersibility in a polyolefin resin, and as a result, without depending on processing conditions, the metal salt of an alicyclic dicarboxylic acid having a very excellent effect of improving crystallinity, which is an essential performance as a nucleating agent for polyolefin resins, The method for producing a metal salt of the alicyclic dicarboxylic acid and a nucleating agent containing the metal salt of the alicyclic dicarboxylic acid, a nucleating agent composition for a polyolefin resin further comprising a metal salt of a fatty acid and the nucleating agent, and the nucleating agent It is an object of the present invention to provide a polyolefin-based resin composition containing, and a polyolefin-based resin molded body using the polyolefin-based resin composition as a raw material. In the present invention, the alicyclic dicarboxylic acid is a cyclohexane-1,2-dicarboxylic acid having an alkyl substituent, and the metal salt is a calcium salt, a hydroxyaluminum salt, a disodium salt, or an alicyclic dicarboxylic acid. It relates to metal salts of carboxylic acids.
