Provided is a fluoride ion secondary battery having high charging and discharging efficiency at room temperature. The fluoride ion secondary battery includes a positive electrode material layer including Ag; a negative electrode material layer including at least one of CeF3 and PbF2; and a solid electrolyte layer including LaF3 and disposed between the positive electrode material layer and the negative electrode material layer. The fluoride ion secondary battery may further include a negative electrode current collector layer disposed on an outer side of the negative electrode material layer. The negative electrode current collector layer may include carbon when the negative electrode material layer includes CeF3 or may include a Pb foil when the negative electrode material layer includes PbF2.
