Abstract
A laminated optical element includes an optical substrate made of an optical material, an intermediate layer provided on the optical substrate, and an optical resin layer provided on the intermediate layer. The optical resin layer is made of a resin composed of an organometallic polymer having an -M-O-M- bond (M is a metal atom), a metal alkoxide and/or a hydrolysate thereof having only one hydrolyzable group, and an organic polymer having a urethane bond and a methacryloxy group or an acryloxy group. The intermediate layer is obtained by dispersing metal oxide microparticles in a matrix resin composed of a metal alkoxide having a radical polymerizable group and a hydrolyzable group and/or a hydrolysate thereof.
