    摘要: A method for manufacturing a sheet having a fine shape transferred thereon, in which a sheet base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet base is then pressed by a pair of pressing plates to imprint the fine shape of surface irregularity of the imprint mold to the sheet-like base. The sheet base is pressed such that, when pressing force of the pressing plates is maximum, an imprinting pressure difference is present in an imprinting surface of the imprint mold, a maximum imprinting pressure section is present in the imprinting surface, and a portion where the imprinting pressure is minimum is not present in the imprinting surface. The method achieves uniform and highly accurate shape transfer without trapping of air.
