Abstract

Provided are a method and an apparatus for manufacturing an optical element, by which high eccentricity accuracy is ensured, in the case of manufacturing the optical element having two facing optical surfaces by a droplet forming method. The method is provided with a heating step of heating a molding die to a prescribed temperature, a dropping step of dropping a molten glass droplet to a lower die, and a pressurization step of forming the optical element by relatively moving an upper die and the lower die in a pressurizing direction and applying pressure to the molten glass droplet. Based on the positional shift quantity of the two optical surfaces of the optical element formed in the pressurization step, at least the relative position or inclination of the upper die and the lower die in the horizontal direction in the pressurization step is adjusted.
