摘要

[Problem] To provide an all-solid-state secondary cell having excellent ion conductivity and moisture resistance, a solid-state electrolyte composition used in the all-solid-state secondary cell, a cell electrode sheet in which the solid-state electrolyte composition is used, a method for manufacturing the cell electrode sheet, and a method for manufacturing the all-solid-state secondary cell. [Solution] An all-solid-state secondary cell having a positive electrode active layer, a negative electrode active layer, and an inorganic solid-state electrolyte layer, wherein any of at least the positive electrode active layer, the negative electrode active layer, or the inorganic solid-state electrolyte layer contains an inorganic solid-state electrolyte represented by formula (1); a solid-state electrolyte composition; a cell electrode sheet; a method for manufacturing the cell electrode sheet; and a method for manufacturing the all-solid-state secondary cell. Li(3-2x)MxDO (1), where x represents a number from 0 to 0.1 inclusive, and M represents a divalent metallic atom. D represents a halogen atom or a combination of two or more halogen atoms.
