Abstract
A method of manufacturing a reinforced plate glass by which glass surface strength is sufficiently increased, and a stable quality reinforced plate glass is manufactured at high production efficiency. The reinforced plate glass is formed of an inorganic oxide glass, and is provided with a compression stress layer by chemical reinforcement on plate surfaces opposed to each other in a plate thickness direction. Plate end faces have regions where a compression stress is formed and regions where no compression stress is formed.
