Abstract
The present invention provides a method for producing a molded article which enables dissolution of a desired amount of a subject material in a molten resin without any limitation by the solubility of a high-pressure carbon dioxide in the molten resin and which is therefore suitable for commercial production of molded articles. The present invention pertains to a method for producing a molded article by molding a molten resin, and this method is characterized by including steps of supplying a high-pressure carbon dioxide and a subject material dissolved therein, into the molten resin; kneading the molten resin into which the high-pressure carbon dioxide and the subject material have been supplied; and exhausting the high-pressure carbon dioxide from the kneaded molten resin.
