Summary:To provide a diaphragm with high Young's modulus.SOLUTION: In a manufacturing method of a diaphragm, a liquid coating solution that contains cellulose nanofibers 121 and diamondoid 122 having multiple functional groups capable of hydrogen bond with OH group of the cellulose nanofibers 121 is applied over the surface of a paper substrate 101 and dried. With this, a reinforced layer 102 containing cellulose nanofibers 121 crosslinked by diamondoid 122 is formed over the surface of the substrate 101.SELECTED DRAWING: Figure 1 【課題】ヤング率の高い振動板を提供する。【解決手段】セルロースナノファイバ１２１、およびセルロースナノファイバ１２１が備えるＯＨ基と水素結合可能な官能基を複数備えるダイヤモンドイド１２２を含む液体である塗布溶液を紙製の基板１０１の表面に塗布し、乾燥させることにより基板１０１の表面にダイヤモンドイド１２２により架橋されたセルロースナノファイバ１２１を含む強化層１０２を形成する振動板の製造方法。【選択図】図１
