An object of the present disclosure is to provide a fluoride ion battery of which power generating elements (a cathode active material layer, a solid electrolyte layer, and an anode active material layer) may be formed by two kinds of members: an electrode layer and a solid electrolyte layer. The present disclosure achieves the object by providing a fluoride ion battery comprising: an electrode layer that includes a first metal element or a carbon element and has capability of fluorination and defluorination; a solid electrolyte layer containing a solid electrolyte material, the solid electrolyte material including a second metal element with lower fluorination potential and defluorination potential than the potentials of the first metal element or the carbon element; and an anode current collector, in this order; and an anode active material layer being not present between the solid electrolyte layer and the anode current collector.
