ABSTRACT:
A holographic optical element or other similar molded article using glass as a substrate is improved in the adhesion between the glass substrate and a resin layer formed thereon so that neither peeling nor change of properties will occur. A holographic optical element (4) is adapted to generate interference fringes of the same pitch as that of tracks formed on a magnetic recording disk or repeated patterns formed on an encoder by interference between two light beams emerging from two different holographic lens regions. The holographic optical element (4) includes a glass substrate (3), a radiation-cured resin layer (2) having a hologram relief pattern on the surface thereof, and a silane coupling agent layer (5) provided between the glass substrate (3) and the radiation-cured resin layer (2).
