PROBLEM TO BE SOLVED: To obtain an injection-molded product hard to cause an involved sink, good in the transfer properties of an embossed surface and having high glossiness without being limited by the average molecular weight of a thermoplastic resin and a resin composition and raising the temperature of the resin and the temperature of a mold to an unnecessarily high temperature. SOLUTION: This injection-molded product is obtained by mixing a molten thermoplastic resin composition with nitrogen of which the pressure is adjusted to atmospheric pressure or more and filling a mold cavity, which is pressurized by nitrogen regulated to atmospheric pressure or more, with the nitrogen-containing thermoplastic resin composition.
