PROBLEM TO BE SOLVED: To provide a method for manufacturing an all-solid power storage device, in which a charge-discharge performance can be enhanced by ensuring the contact area between two electrolyte layers of positive and negative electrode layer sides.SOLUTION: A method for manufacturing an all-solid power storage device comprises the steps of: forming a positive electrode current collector on a first insulative substrate; forming a positive electrode layer on the positive electrode current collector; forming a first solid electrolyte layer on the positive electrode layer; forming a negative electrode current collector on a second insulative substrate; forming a negative electrode layer on the negative electrode current collector; forming a second solid electrolyte layer on the negative electrode layer; forming an adhesive solid electrolyte layer on at least one of the first and second solid electrolyte layers; and bonding, by the adhesive solid electrolyte layer, the first and second solid electrolyte layers to each other. The adhesive solid electrolyte layer includes a polymer electrolyte showing stickiness.SELECTED DRAWING: Figure 1 【課題】正極層側と負極層側の２つの電解質層間の接触面積を確保して充放電性能を高めることのできる、全固体蓄電デバイスの製造方法を提供する。【解決手段】第１絶縁基板上に正極集電体を形成する工程と、正極集電体上に正極層を形成する工程と、正極層上に第１固体電解質層を形成する工程と、第２絶縁基板上に負極集電体を形成する工程と、負極集電体上に負極層を形成する工程と、負極層上に第２固体電解質層を形成する工程と、第１固体電解質層上及び第２固体電解質層上の少なくとも一方に粘着性固体電解質層を形成する工程と、粘着性固体電解質層によって第１固体電解質層と第２固体電解質層を互いに接合する接合工程とを有し、粘着性固体電解質層は粘着性を示すポリマー電解質を含む。【選択図】図１
