Abstract: A solid electrolyte material of the present disclosure includes Li, Zr, and F. A ratio of an amount of substance of Li to an amount of substance of Zr is 3.5 or more. In an X-ray diffraction pattern obtained by an X-ray diffraction measurement of the solid electrolyte material using a Cu-Kα ray, a ratio of a value of a full width at half maximum of a peak having a highest intensity within a range of a diffraction angle 2θ from 42.5° to 44.7° to a value of a full width at half maximum of a peak corresponding to a (111) plane of Si in an X-ray diffraction pattern of Si measured under a same condition as in the X-ray diffraction measurement is more than 1.19.
