Abstract
Provided is a method capable of producing a glass sheet with a bent portion with a high form accuracy. A reinforced glass sheet 1 with a flattened portion 11 and bent portions 12a and 13a continued to the flattened portion 11 is produced. A reinforcement step and a deformation step are performed. At the reinforcement step, a flat glass sheet is chemically reinforced to obtain a reinforced flat glass sheet 50. At the deformation step, the reinforced flat glass sheet 50 is heated and deformed to obtain the reinforced glass sheet 1 with the flattened portion 11 and the bent portions 12a and 13a.
