To provide a method for manufacturing a flexible laminate including a circularly polarizing plate, a water-based adhesive layer, and an organic EL panel, which can be laminated with a water-based adhesive without causing deterioration of the organic EL panel due to water vapor.SOLUTION: A method for manufacturing a flexible laminate includes, in this order, a first step of forming a coating film of a water-based adhesive on a circularly polarizing plate, a second step of drying the coating film of the water-based adhesive to form a water-based adhesive layer, and a third step of bonding the circularly polarizing plate and an organic EL panel via the water-based adhesive layer after applying surface activation treatment to the surface of the water-based adhesive layer.SELECTED DRAWING: None 【課題】円偏光板と、水系接着剤層と、有機ＥＬパネルとを備えるフレキシブル積層体の製造方法であって、有機ＥＬパネルの水蒸気による劣化を生じさせずに水系接着剤により貼合することができるフレキシブル積層体の製造方法を提供すること。【解決手段】円偏光板上に、水系接着剤の塗膜を形成する第１工程と、前記水系接着剤の塗膜を乾燥させて、水系接着剤層を形成する第２工程と、前記水系接着剤層の表面に表面活性化処理を施した後、前記円偏光板と有機ＥＬパネルとを前記水系接着剤層を介して貼合する第３工程とをこの順に備える、フレキシブル積層体の製造方法。【選択図】なし
