Abstract
A method for manufacturing a molded product with fine structure includes steps of, in a temperature-controlled stamper mold provided with a fine structure including a concavo-convex pattern having a width of 10 nm to 1 μm, forming a thermoplastic molten polymer layer to be in contact with the fine structureof the stamper mold having been kept at a predetermined temperature and holding the thermoplastic molten polymer layer for a predetermined time so as to transfer the fine structure of the stamper mold to the thermoplastic molten polymer layer under gravity.
