PROBLEM TO BE SOLVED: To hold a resin temperature and a mold temperature to the limits without making these temperatures higher than necessary when injection-molding a polyamide resin and make it possible to easily fill a mold cavity with a molten polyamide resin composition and obtain an injection-molded product made of the polyamide resin composition, finished in a highly precise, more thin-walled and more complicated shape. SOLUTION: The molded product of the polyamide resin composition is constituted of at least (A) a polyamide resin, at least (B) one kind of fibrous inorganic and organic filler. After the molten polyamide resin composition and a carbon dioxide staying within a pressure range not exceeding a critical pressure are mixed, the mixture is packed into the mold cavity.
