Abstract
At a room temperature, cleaned glass substrates 8a, 8b are suitably positioned and placed one upon another. A hydrofluoric acid solution or alkaline solution 10 is dropped into the bonding interface between the glass substrates 8a, 8b. The hydrofluoric acid solution or alkaline solution thus dropped spreads along the bonding interface. At a room temperature, a load is then applied to the upper glass substrate 8a and allowed to stand for a suitable period of time, thus bonding the glass substrates to each other.
