1. A car comprising a fluoride ion battery,
wherein the fluoride ion battery comprises a cathode active material layer, an anode active material layer, and an electrolyte layer formed between the cathode active material layer and the anode active material layer,
wherein the cathode active material layer contains a cathode active material comprising:
a composition represented by Pb2FeF6; and
a peak at a position of 2θ=27.1°±1.0° and 31.3°±1.0° in an X-ray diffraction measurement using a CuKα-ray,
wherein the cathode active material layer further contains a conductive material comprising at least one selected from the group consisting of a carbon black, a graphene, a fullerene, and a carbon nanotube, and
wherein a content of the conductive material in the cathode active material layer is 10 weight % or less.
