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. n 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. |
