Abstract
An optical element manufacturing apparatus is provided with a fixed side metal moldattached to a fixed platen, and a movable side metal moldattached to a movable platen. The fixed side metal moldand the movable side metal moldare clamped by bringing both platensandclose to each other. In the clamped status, a molding material is injected into a molding cavity between the both metal molds and an optical element is produced. A taper recessed sectionand a taper protruding section, provided on the fixed side metal moldand the movable side metal moldrespectively, fit each other. The movable side metal moldprovides a friction mechanism sectionwhich permits the metal mold to shift within a plane perpendicular to the clamping direction with respect to the movable platen.
