SOLID ELECTROLYTE MATERIAL AND BATTERY USING SAME

A solid electrolyte material of the present disclosure includes: Li; Zr; Fe; O; and X. The X is at least one selected from the group consisting of F, Cl, Br, and I. In an X-ray diffraction pattern obtained by X-ray diffraction measurement using a Cu-Kα ray, a first peak is present within a range of a diffraction angle 2θ from 14.7° to 15.1°, a second peak is present within a range of the diffraction angle 2θ from 29.9° to 30.7°, and a third peak is present within a range of the diffraction angle 2θ from 34.1° to 34.8°.
