Claim 7:
8. A method of manufacturing an electrode sheet for an all-solid state secondary battery, the electrode sheet for an all-solid state secondary battery comprises one of a positive electrode active material layer or a negative electrode active material layer; and a solid electrolyte layer that is laminated on the active material layer, wherein the solid electrolyte layer includes a binder consisting of a polymer and an inorganic solid electrolyte and has unevenness on a surface, whose recess portions are formed in a state where 1% to 10 mass % of the solid electrolyte layer with respect to the total mass of the inorganic solid electrolyte layer falls out,
the method comprising:
a pre-compression bonding step of laminating a solid electrolyte layer and one of a positive electrode active material layer or a negative electrode active material layer to form a laminate and compressing the laminate to bond the layers, the solid electrolyte layer being formed on a support; and
a step of peeling off the support from the solid electrolyte layer such that 1% to 10 mass % of the solid electrolyte layer that is compressed and bonded to the active material layer remains in the support.
