Abstract: Provided is a solid electrolyte material composed of Li, M, and X, where M is at least one kind of element selected from the group consisting of metalloid elements and metallic elements other than Li, and X is at least one kind of element selected from the group consisting of F, Cl, Br and I. In the solid electrolyte material, the mathematical formula FWHM/2θp≤0.015 is satisfied, where FWHM represents a half bandwidth of an X-ray diffraction peak having the highest intensity within a range of a diffraction angle 2θ of not less than 25 degrees and not more than 35 degrees in an X-ray diffraction pattern provided by an X-ray diffraction measurement of the solid electrolyte material; the X-ray diffraction measurement using a Cu-Kα ray; and 2θp represents a diffraction angle of a center of the X-ray diffraction peak. A value rCA provided by dividing a sum of ionic radii of Li and M by a sum of ionic radii of X is more than 0.261 and less than 0.306. A value of a difference ΔX between average electronegativity of M and average electronegativity of X is not less than 1.7.
