Method for manufacturing tempered glass plate
A method for manufacturing a tempered glass plate is provided, which is characterized in including: an arranging step in which a plurality of erected glass plates for temper which is almost rectangle and has 1.0 mm or less of thickness are arranged on a support with 10 mm or less of interval in thickness direction so as to obtain a glass plate for temper-arranged body; a tempering step in which the glass plate for temper-arranged body is dipped in an ion exchange solution to perform an ion exchange treatment so as to obtain a tempered glass plate-arranged body; a slow cooling step in which the tempered glass plate-arranged body is taken out from the ion exchange solution for slow cooling; and a taking-out step in which each tempered glass plate which constructs the tempered glass plate arranged-body is taken out from the support.
