Zusammenfassung:	A process for manufacturing a laminated glass including an intermediate film containing EVA as a main component is provided. In the process, the laminated glass is manufactured through a step wherein a pressure is applied to a laminate by nip rolls. By the process, bubble formation in the laminated glass can be satisfactorily prevented. The process for manufacturing the laminated glass is characterized by including a step for preparing a laminate 20 containing an intermediate film 12 having at least one ethylene-vinyl acetate copolymer layer including ethylene-vinyl acetate copolymer and a crosslinking agent, having a melt viscosity at 70°C of 2 × 10 5 Pa · s or less, an arithmetic mean estimation Ra (JIS-B0601(2001)) of at least on one surface in the range of 5 to 20 µ m, and a mean thickness of 0.5 mm or more, and at least two glass plates, the intermediate film interposed between the at least two glass plates; a step for compacting the laminate 20 by being pressurized by nip rolls 34 after being heated; and a step for integrating the laminate by crosslinking by heating after the step for compacting the laminate.
