摘要： A manufacturing method uses a molding unit to manufacture lenses out of a structure with a plurality of lens intermediates coupled to each other through a runner. The molding unit includes a holding member provided with first opening parts and second opening parts coaxial with each other, and molding chambers. First molding dies and second molding dies are inserted into the first opening parts and the second opening parts respectively. The holding member is further provided with a path that allows introduction of the lens intermediates into the molding chambers. In a manufacturing process, the lens intermediates are guided to predetermined positions in the corresponding molding chambers by operating the structure to cause the lens intermediates and the runner to move along the path. Next, a pressing pressure is applied to the lens intermediates to form molded lenses.
