(57) [Abstract] [Purpose] To provide a method for manufacturing glass microspheres that can be used for microoptical parts, microsphere lasers, and the like. [Structure] After melting a glass raw material or glass itself to form a glass melt, the glass melt is dropped into a cooling liquid. The cooling liquid is liquid nitrogen, carbon tetrachloride, chlorofluorocarbon, or the like, which does not decompose at the temperature of the dropped glass melt. |
