Provided is a solid electrolyte laminated sheet having a self-supporting property and capable of realizing a solid state battery having high output characteristics. A plurality of supports are used, a solid electrolyte is filled in each support to form a self-supporting sheet, and the self-supporting sheets are superimposed to form a solid electrolyte laminated sheet. Specifically, the solid electrolyte laminated sheet is configured by setting a layer of the solid electrolyte laminated sheet in contact with a positive electrode layer being the outermost layer as a self-supporting sheet in which a solid electrolyte resistant to oxidation is filled, and a layer in contact with a negative electrode layer being the opposite outermost layer as a self-supporting sheet in which a solid electrolyte resistant to reduction is filled.
