Provided is a process for producing a laminated glass including an interlayer containing EVA as the main component through steps which include pressing with nip rolls. With the process, it is possible to satisfactorily remove air bubbles from a laminated glass. The process for producing a laminated glass is characterized by comprising: a step in which an interlayer (12) comprising one or more ethylene/vinyl acetate copolymer layers which each comprises a composition comprising an ethylene/vinyl acetate copolymer and a crosslinking agent and which each has a melt viscosity at 70ºC of 2×105 Pa·s or less, an arithmetic-mean roughness, Ra (JIS-B0601 (2001)), of at least one surface thereof of 5-20 µm, and an average thickness of 0.5 mm or more is sandwiched between two or more glass sheets to obtain a stack (20); a press-bonding step in which the stack (20) is heated and then pressed with nip rolls (34) to press-bond the stack; and a step in which after the press-bonding step, the resultant laminate is further heated to crosslink the copolymer and integrate the interlayer with the glass sheets. |
