This production method for a sheet glass comprises an end surface processing step for processing an end surface ES of a sheet glass G using at least one processing tool 2. The processing tool 2 includes a constant-pressure processing tool which makes contact with the end surface ES of the sheet glass G at a constant pressure. In the end surface processing step, an abnormal recess and protrusion UD1, UD2 occurring on the end surface ES of the sheet glass G is detected, on the basis of positional information of the constant-pressure processing tool 2, by a control device 5 which preforms position control of the constant-pressure processing tool 2.
