PROBLEM TO BE SOLVED: To provide a method for producing a glass plate which can easily produce a curved surface glass plate.SOLUTION: A method for producing a glass plate includes a molding process (a step S11) in which molten glass is molded into a glass ribbon in a shape of a strip, an annealing process (a step S12) in which the glass ribbon is annealed while being conveyed in a prescribed direction, a cutting process (a step S13) in which a glass plate is cut out from the annealed glass ribbon. In the annealing process (the step S12), when the glass ribbon is passed through a temperature range in the vicinity of the strain point of the glass, the temperatures of the front and rear of the glass ribbon are made different. |
