Abstract
A method of manufacturing a sheet glass includes: a re-draw process forming a sheet glass by, heating and softening a glass preform manufactured by float method, and extending the glass preform to a desirable plate thickness. An extension direction in which the glass preform is extended by the re-draw process is 90 degrees with respect to a direction in which molten glass is fed in the float method.
