Abstract
The present invention provides a substrate provided with an optical structure which can correctly transfer the jagged shape of a mold and guarantee a lens surface that has favorable quality, and provides an optical element which uses such a substrate. A manufacturing method of a substrate, provided with an optical structure, includes applying a curing resin onto the substrate, which has a recessed portion, pressing a mold, having a jagged shape, from an upper portion of the curing resin toward the substrate, and forming an optical structure having the jagged shape by curing the curing resin. The recessed portion is provided to cover the lower portion of the region on which the jagged shape is arranged, so as to retain uncured resin of the curing resin when the mold is pressed toward the substrate. An optical element includes a substrate that is manufactured using the above-described manufacturing method.
