PROBLEM TO BE SOLVED: To provide a solid electrolyte for an all-solid-state ion secondary battery, in which resistance to reduction is compatible with ion conductivity.SOLUTION: This all-solid-state ion secondary battery includes a positive electrode active material layer which contains a solid electrolyte having a ramsdellite type crystal structure expressed by LiSnO(0<x<1.33), particles containing the solid electrolyte, a positive electrode material, and an oxide softened and fluidized at lower temperatures in comparison with the solid electrolyte while having ion conductivity, and in which the particles and the positive electrode active material are bound by the oxide, a negative electrode active material layer which contains particles containing the solid electrolyte, a negative electrode active material, and an oxide softened and fluidized at lower temperatures in comparison with the solid electrolyte, and in which the particles and the negative electrode active material are bound by the oxide, and a solid electrolyte layer containing the solid electrolyte. The solid electrolyte layer is bonded between the positive electrode active material layer and the negative electrode layer. |
