Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminated glass maintaining excellent appearance characteristics for a long time after manufacturing.
SOLUTION: The method comprises the steps of: making a laminate by inserting an interlayer film for the laminated glass including a copolymer of ethylene and a polar monomer, and a cross-linking agent between two transparent substrates; a preliminary pressure-sticking process of heating the laminate at a temperature from Tm to Tm+25°C under vacuum; a tentative adhesion process of heating the laminate at a temperature from Tm+20°C to Tm+45°C under the vacuum lower than that of the preliminary pressure-sticking process, and a main adhesion process of heating the laminate at a temperature from Tm+30°C to Tm+60°C under normal pressure where Tm is a melting point of the copolymer of ethylene and the polar monomer, wherein a heat treatment temperature (T
1 ) in the preliminary pressure-sticking process, a heat treatment temperature (T
2 ) in the tentative adhesion process, and a heat treatment temperature (T
3 ) in the main adhesion process satisfy the relation of T
1 2 3 .
