摘要： In a method of manufacturing a glass molding, a lower mold includes a recess having a bottom portion and a side portion surrounding the bottom portion, and an outer peripheral planar portion surrounding an upper end of the side portion. A crossing angle between the side portion and the outer peripheral planar portion is set at more than or equal to 45 degrees. A dropping volume of the molten glass drop is such that, when dropped onto the lower mold, a volume of the molten glass drop located above the outer peripheral planar portion is 1.5 times to 6.0 times the volume of the molten glass drop filling the recess.

摘要： A manufacturing apparatus of the present invention has a pair of dies that form each cylindrical surface, and a plane member that forms side surfaces of an element. The upper die and the lower die has a cylindrical surface which is worked so as to have generatrix which connects intersection points between a non-arc axis and a cylindrical section and between an arc center axis and the cylindrical section. The plane member is pressed against reference surfaces of the upper die and the lower die. In this state, a glass material is put between the upper die and the lower die, and a distance between the upper die and the lower die is decreased. As a result, the cylindrical surfaces of the upper die and the lower die and the plane of the plane member are transferred onto the glass material.
