<p>PROBLEM TO BE SOLVED: To provide a manufacturing method for laminate glass in which a laminate glass with superior optical characteristics can be obtained.SOLUTION: There is provided a manufacturing method for laminate glass in which a laminate glass is obtained, the manufacturing method including: a pressure reduction process of creating a vacuum state of 3 Pa or lower by reducing the pressure in a chamber in which a plurality of glass plates are accommodated apart from each other; a lamination process in which the glass plates are put one over the other in the chamber in the vacuum state so as to form a laminate; a heating process of heating the laminate; and a pressing process of pressing the laminate. The heating temperature in the heating process is equal to or higher than the lowest temperature among temperatures at which the glass plates have a viscosity of logη=11.5.</p> |
