Abstract
A plurality of glass plates 10 are stacked in a block form without forming gaps between adjacent glass plates while the stacked glass plates are separable; the stacked glass plates are cut off in a circular shape or a doughnut-like shape in a block; and then, the processed glass plates are separated. According to this method, tipping which may result when glass plates are processed individually can be prevented whereby processing is easy, and productivity is improved.
