PROBLEM TO BE SOLVED: To provide a method for producing a PVB member, capable of obtaining a PVB member having high smoothness.SOLUTION: The method for producing a PVB member comprises the steps of: (a) arranging an organic release sheet on a first surface of a PVB sheet having the first surface and a second surface to constitute a laminate; (b) heating and compressing the laminate at 120-150°C; and (c) removing the organic release sheet from the laminate after the heating and compression.SELECTED DRAWING: Figure 2 【課題】平滑性の高いＰＶＢ部材を得ることが可能な、ＰＶＢ部材の製造方法を提供する。【解決手段】ＰＶＢ部材の製造方法であって、（ａ）第１および第２の表面を有するＰＶＢシートの第１の表面に、有機剥離シートを配置して、積層体を構成するステップと、（ｂ）前記積層体を、１２０℃〜１５０℃で加熱圧縮するステップと、（ｃ）加熱圧縮後の前記積層体から、前記有機剥離シートを除去するステップと、を有する製造方法。【選択図】図２
