摘要

PURPOSE:To produce a sheet wherein air bubbles are not mixed and the thickness of the resin formed on a base member is uniform. CONSTITUTION:In a process producing a sheet constituted by forming a fine pattern parts of Flesnel lenses composed of a reactive curable resin on a base member 1, the base member 1 is placed on the reactive curable resin 2 applied to a mold 3 to be pressed by a pressure roll 4. In this case, the pressure roll 4 wherein the diameter of the central part thereof is different from that of each of both end parts thereof is used and the reactive curable resin 2 is pressed while leveled to laminate the base member 1 on the resin.
