PROBLEM TO BE SOLVED: To provide a composite film in which no bubble is present in an adhesive layer via which a resin film and glass film are adhesively bonded to each other.SOLUTION: A method for producing a composite film includes: a step of producing a layered body L having a layered structure in which a glass film G2 is layered on a resin film R1 via an uncured adhesive layer A2; and a step of pressing a roller 25 toward a second principal surface LS2 of the layered body L while moving the roller along a first principal surface LS1 of the layered body L. The roller 25 is moved in a first direction F along the first principal surface LS1 in a first pressing state and then moved in a second direction B opposite to the first direction F along the first principal surface LS1 in a second pressing state.SELECTED DRAWING: Figure 3 【課題】樹脂フィルムとガラスフィルムを接着する接着層に気泡のない複合フィルムを提供する。【解決手段】複合フィルムの製造方法であって、樹脂フィルムＲ１に未硬化の接着層Ａ２を介してガラスフィルムＧ２を積層した積層構造を有する積層体Ｌを製造する工程と、ローラ２５を積層体Ｌの第１の主表面ＬＳ１に沿って移動させながら、積層体Ｌの第２の主表面ＬＳ２側に押圧する工程とを備えている。ローラ２５は、第１の押圧状態で第１の主表面ＬＳ１に沿って第１の方向Ｆに移動した後、第２の押圧状態で第１の主表面ＬＳ１に沿って第１の方向Ｆとは反対の第２の方向Ｂに移動する。【選択図】図３
