Abstract: Provided is a solid electrolyte material for fluoride ion batteries which has high fluoride ion conductivity. The solid electrolyte material for fluoride ion batteries includes a metal composite fluoride that includes, as its main phase, a crystal structure containing, in a fluorite structure containing a fluoride ion, a lanthanoid metal ion, and an alkali earth metal ion, an adduct ion having an ion radius larger than that of the alkali earth metal ion. The metal composite fluoride has a composition in which a ratio of a number of moles of the fluoride ion to a total number of moles of the lanthanoid metal ion, the alkali earth metal ion, and the adduct ion is greater than 1.87 and is smaller than 3, and a ratio of a number of moles of the adduct ion to a number of moles of the alkali earth metal ion is smaller than 1.
