The present invention aims to provide a method for improving the fluidity of a crystal nucleating agent for polyolefin resins, a method for producing a crystal nucleating agent for polyolefin resins with improved fluidity including the above method, a crystal nucleating agent for polyolefin resins with improved fluidity obtained by the method, and a highly transparent polyolefin resin composition and a molded article thereof each prepared using the crystal nucleating agent. The present invention provides a crystal nucleating agent for polyolefin resins wherein the crystal nucleating agent has an angle of repose within a specific range, and a 1-mm-thick polyolefin resin molded article produced using the crystal nucleating agent has a haze value within a specific range. The crystal nucleating agent for polyolefin resins has excellent dispersibility or solubility in resin and exhibits remarkably improved fluidity. Use of the crystal nucleating agent enables easy production of a polyolefin resin composition having a very excellent transparency and a molded article thereof.
