<P>PROBLEM TO BE SOLVED: To provide an optical element improving durability of a mold by reducing demolding force in starting demolding, controlling a start point and a direction of the demolding, and preventing peeling, deformation and breakage of a resin from a glass board. <P>SOLUTION: The optical element forming a light energy curable resin has a required shape on a base material by demolding a light energy curable resin after curing it by shape transfer and light irradiation by using the mold. Two regions different in the demolding exist on a resin/mold interface, the inside has an inferior demolding region, the outside has a good demolding region, and the optical element has a projection-like shape in viewing from an orthogonal direction to a base material face of an outer peripheral part of the inferior demolding region. <P>COPYRIGHT: (C)2003,JPO |
