摘要： A glass material is press-molded by an upper die and a lower die in a closed space, so that an optical element is manufactured. A temperature variation of an atmosphere in the closed space is controlled within ±0.5° C. The glass material is dropped from a nozzle of a fusion furnace onto the lower die. A dropping space between the nozzle and the lower die which receives molten glass droplets is surrounded by an enclosure. Further, a die moving space in which the lower die moves from the dropping position where the molten glass is dropped to a molding position where the upper die stands by is enclosed by another enclosure. The molten glass dropped from the nozzle of the fusion furnace is press-molded in an atmosphere of stable temperature, so that optical glass elements with less variation can be manufactured.
