Provided is a method for producing a nucleator masterbatch, which is able to produce a nucleator masterbatch that is capable of improving the transparency and physical properties of an olefin resin. A method for producing a nucleator masterbatch obtained by blending a nucleator with an olefin polymer, which is characterized by comprising a step wherein an olefin monomer is polymerized, while blending a material that is obtained by dissolving a nucleator component in an organic aluminum compound or in an organic aluminum compound and an organic solvent before or during the polymerization of the olefin monomer such that the amount of the nucleator component is 0.05-20 parts by mass relative to 100 parts by mass of the olefin polymer that is obtained by polymerizing the olefin monomer. |
