Provided is a method for producing laminated glass in which a gap does not readily occur when a resin film is fitted into an opening of an intermediate film. This method for producing laminated glass has a step for producing an intermediate film, and a step for disposing the intermediate film between a first glass plate and a second glass plate and performing pressure bonding. The step of manufacturing the intermediate film includes a step of forming an opening in the first resin film, a step of cutting the second resin film into a shape larger than the area of the opening to form a third resin film, and a step of embedding the third resin film into the opening. 本发明提供一种将树脂膜嵌入中间膜的开口部时不容易产生间隙的夹层玻璃的制造方法。本夹层玻璃的制造方法具有制作中间膜的工序、在第1玻璃板与第2玻璃板之间配置所述中间膜而进行压接的工序，所述制作中间膜的工序包括在第1树脂膜形成开口部的工序、将第2树脂膜切割成比所述开口部面积更大的形状以形成第3树脂膜的工序、将所述第3树脂膜嵌入所述开口部的工序。
