Abstract
A main object of the present disclosure is to provide a solid electrolyte including excellent fluoride ion conductivity. The present disclosure achieves the object by providing a solid electrolyte including fluoride ion conductivity, the solid electrolyte comprising: a crystal phase having a perovskite structure or a layered perovskite structure; the crystal phase contains A cation positioned in A site, B cation positioned in B site, and a fluoride ion; the A cation contains R1R2R3R4N+ cation (each of R1 to R4 is independently a hydrogen element or a hydrocarbon group with two or less carbon atoms) or a hydrocarbon cation with two or less carbon atoms; and the B cation contains a divalent metal cation and a monovalent metal cation.
