In a method for manufacturing a glass plate that includes chamfering processing for chamfering an edge surface of a glass plate, the chamfering 5 processing includes a step of forming a chamfered surface by irradiating the edge surface of the glass plate with a laser beam, and a step of heating the glass plate before the chamfered surface is formed. When a temperature of the glass blank at which the glass blank is heated is Tp ['C], a glass transition point of the glass blank is Tg ['C], and an average coefficient of linear thermal expansion 10 of the glassblankiso [U"C], (Tg-Tp)S -5.67 x 107. o+840issatisfied.
