An optical molding apparatus molds an optically molded product by stacking cured layers. Each cured layer is formed by emitting light according to cross-sectional-shape data of the optically molded product onto a surface of photo-curable resin. The optical molding apparatus includes an exposing unit and an exposure control unit. The exposing unit performs exposure on the photo-curable resin for each of small work areas that are defined by dividing an overall work area, which is where an optical molding operation is performed, into a plurality of areas. The exposure control unit controls an exposure condition of the exposing unit for each of the small work areas and allows the exposure to be performed collectively on multiple layers' worth of the photo-curable resin in a predetermined one of the small work areas.
