Abstract

For generation of optical elements, a master prototype, a resin master, a resin molded article or a metal mold is used. In the master prototype, the resin master, the resin molded article or the metal mold, a fine relief structure is formed on a plane through which an object light is transmitted at a pitch smaller than a wavelength band of the object light, an identification pattern region is disposed in a part of a region where fine relief structure is formed, and in the identification pattern region, a state of the fine relief structure is different from that in the other region. An actual manufacturer of the master prototype, the resin master, the resin molded article or the metal mold can be identified by physically verifying the identification pattern region.
