PURPOSE:To freely select the thickness and material quality of a base material and to easily release a mold and a resin layer without deforming and damaging the base material at a time of the release of the mold and the resin layer. CONSTITUTION:An energy curable resin is placed on the upper surface of a base material 2 and a mold 1 for molding an optical element is pressed to the resin to form a desired resin layer 3. Next, the resin layer 3 is cured by the irradiation with energy and the cured resin layer 3 is released from the mold 1. At this time, the surface 2a capable of being subjected to the face contact with a release member 4 is provided to the optical effective diameter outer peripheral part of the molding surface or side surface of the base material 2 and the base material 2 and the release member 4 are brought to a face contact state through the surface 2a to release the mold 1 and the resin layer 3. |
