Claim:
1. A method for manufacturing a molded product with fine structure, comprising steps of: in a temperature-controlled stamper mold having a fine structure comprising a concavo-convex pattern having a width of 10 nm to 1 μm, coating a thermoplastic polymer onto the mold by discharging the thermoplastic polymer from a polymer discharge port of a T die while moving the T die over the mold and forming a thermoplastic molten polymer layer to be in contact with the fine structure of the stamper mold having been kept at a predetermined temperature; holding the thermoplastic molten polymer layer for a predetermined time so as to transcribe the fine structure of the stamper mold to the thermoplastic molten polymer layer under gravity so that the nano-sized fine pattern is transcribed to the thermoplastic molten polymer without pressurization by a pressurization apparatus; cooling and solidifying the transcribed thermoplastic molten polymer layer; and subsequently releasing the solidified thermoplastic molten polymer layer from the stamper mold.
