An oxyhalide material of the present disclosure contains Li, M, O, and X. M is at least two selected from Group 5 elements. X is at least one selected from the group consisting of F, Cl, Br, and I. The oxyhalide material of the present disclosure shows a reversible oxidation-reduction reaction. In an X-ray diffraction pattern obtained by X-ray diffraction measurement on the oxyhalide material using Cu-Kα radiation, at least one peak is present in a first range, and (A) or (B) below is satisfied: (A) No peak is present in a second range. (B) At least one peak is present in the second range, and a ratio of intensity Ip1 of a peak with the highest intensity present in the first range to intensity Ip2 of a peak with the highest intensity present in the second range Ip1/Ip2 is larger than 5.
