Abstract
A process for cutting a sheet glass includes a first step of forming a groove conformed to a cutting shape in one surface of a sheet glass by a water jet, and a second step of forming a groove in the other surface of the sheet glass by a water jet to reach the groove, which are carried out sequentially, thereby cutting the sheet glass. Thus, the sheet glass can be cut by the water jets, while preventing occurrence of breaking or cranking, without need for a post-processing.
