Zusammenfassung:	To provide a manufacturing method of an optical laminate capable of preventing a curl.SOLUTION: A manufacturing method of an optical laminate 100 includes: a separator bonding process ST4 of bonding a separator 4 onto a polarizer 10 interposing an adhesive layer 3 formed on the separator; and a separator peeling/bonding process ST5 of separating the separator from the adhesive layer after the separator bonding process, then bonding the separator interposing the adhesive layer to the polarizer. In the separator peeling/bonding process, at least the separation of the separator is executed in an environment humidified to absolute humidity 10 g/m3 or more.SELECTED DRAWING: Figure 2 【課題】カールを抑制可能な光学積層体の製造方法を提供する。【解決手段】本発明に係る光学積層体１００の製造方法は、セパレータ４に形成された粘着剤層３を介してセパレータを偏光板１０に貼り合わせるセパレータ貼合工程ＳＴ４と、セパレータ貼合工程の後に、セパレータを粘着剤層から剥離した後、セパレータを粘着剤層を介して偏光板に貼り合わせるセパレータ剥離・貼合工程ＳＴ５と、を含む。セパレータ剥離・貼合工程において、少なくともセパレータの剥離が絶対湿度１０ｇ／ｍ３以上に加湿された環境下で実行される。【選択図】図２
