摘要：
A glass block is formed by stacking, fixing, and integrating a plurality of thin glass plates having a predetermined thickness. An annular glass block is formed by coring the glass block. Surfaces of an inside circumference and an outside circumference of the annular glass block are ground. The annular glass block of which the surfaces of the inside circumference and the outside circumference are ground are separated into individual annular glass substrates, and separated annular glass substrates are cleaned. Then, edge portions of the inside circumference and the outside circumference of a cleaned annular glass substrate are chamfered.
