To provide a method for producing a laminate having a functional layer that is ideal for use in a variety of industrial applications.SOLUTION: A method for producing a laminate includes forming a functional layer containing an anionically modified cellulose nanofiber on a transfer substrate and then bonding a support substrate onto the functional layer, before peeling the functional layer from the transfer substrate, so that the functional layer containing the anionically modified cellulose nanofiber is formed on the support substrate. The support substrate and the functional layer form a laminate through a reception layer.SELECTED DRAWING: None 【課題】本発明によれば、様々な工業用途に適用させるために最適な機能層を持つ積層体の製造方法を提供することを課題とする。【解決手段】転写用基材上にアニオン変性セルロースナノファイバーを含む機能層を形成した後、該機能層の面上に支持基材を貼合し、次いで該転写用基材から機能層を剥離させ、該支持基材上にアニオン変性セルロースナノファイバーを含む機能層を形成させることを特徴とする、前記支持基材と前記機能層とが、受容層を介して積層体を形成させることを特徴とする積層体の製造方法。【選択図】なし
