To provide a method for producing a laminate capable of facilitating an operation of laminating a second layer on a first layer.SOLUTION: A method for producing a laminate where a second layer and a first layer as a green sheet are superimposed, comprises the steps of: applying slurry to form into the second layer to a green sheet; and drying the slurry applied to the green sheet to obtain the second layer. A difference between a solubility parameter P1 of a first binder included in the green sheet and a solubility parameter P2 of a solvent included in the slurry is 3.97 MPa1/2 or higher.SELECTED DRAWING: Figure 2 【課題】第１の層に第２の層を積層する作業を簡易にできる積層体の製造方法を提供すること。【解決手段】積層体の製造方法は、第２の層とグリーンシートである第１の層とが重なり合った積層体の製造方法であって、第２の層となるスラリーをグリーンシートに塗布する工程と、グリーンシートに塗布されたスラリーを乾燥し第２の層を得る工程と、を備え、グリーンシートに含まれる第１バインダーの溶解度パラメータＰ１とスラリーに含まれる溶剤の溶解度パラメータＰ２との差は３．９７ＭＰａ１／２以上である。【選択図】図２
