To provide a manufacturing method for a molded sheet wherein even when preparation of a mold is performed in a short time and at a low cost, mounting the mold on a manufacturing apparatus can be done by a simple constitution, and strength to pressurizing by a press roll and strength enough durable to a force applied during releasing is sufficient, in the method for manufacturing a sheet with an unevenness represented by a lens sheet prepared by a cured article of a UV-curable resin or the like.

The manufacturing is performed under a condition where a flat sheet-like stamper on the molding face of which a reverse shape of an uneven shape existing on the surface of an aimed manufacturing product is formed, is mounted and fixed on a base sheet with a larger area than that of the stamper.
