A method for manufacturing a sheet having a shape transferred thereon, in which a sheet-like base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet-like base is then pressed by a pair of pressing plates to imprint the shape of surface irregularity of the imprint mold to the sheet-like base. The sheet-like 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.
