摘要： Disclosed herein is a reliable laminated optical element that is a hybrid optical element obtained by laminating an optical resin layer on an optical substrate such as a glass substrate, the optical resin layer being less likely to be separated from the optical substrate even under high temperature and high humidity conditions.The laminated optical element comprises an optical substrate 1 made of an optical material, an intermediate layer 2 provided on the optical substrate 1, and an optical resin layer 3 provided on the intermediate layer 2. The optical resin layer 3 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 2 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.
