Abstract
An apparatus for forming an optical element. The apparatus includes a pair of forming molds each of which has a facing surface facing each other. At least one of the pair of the forming molds is made so as to allow a hardening energy to pass through itself. A frame-like mold member is provided so as to be interposed between the facing surfaces of the pair of the forming molds to cover an outer peripheral portion which each of the forming molds has on its facing surface, thereby defining a cavity. In the thus arranged apparatus, an energy hardening resin is filled into the cavity and then hardened by being subjected to the hardening energy passing through the at least one of the pair of the forming molds.
