1. A solid electrolyte material represented by the following Compositional Formula (1):
Li6-3zYzX6
where 0<z<2 is satisfied; and
X represents Br;
wherein
the solid electrolyte material includes at least one fourth crystal phase; and
the fourth crystal phase shows, in structural analysis of the fourth crystal phase through X-ray diffractometry by a θ-2θ method using Cu—Kα rays having wavelengths of 1.5405 angstrom and 1.5444 angstrom as the X-ray, peaks within ranges of diffraction angle 2θ values of 13.1° to 14.5°, 26.6° to 28.3°, 30.8° to 32.7°, 44.2° to 47.1°, 52.3° to 55.8°, and 54.8° to 58.5°;
and wherein:
FWHM4 denoting a full width at half maximum of the X-ray diffraction peak observed within the range of 26.6° to 28.3° in the X-ray diffractometry using Cu—Kα rays, and
2θc4 denoting a diffraction angle at the center of the X-ray diffraction peak satisfy:
FWHM4/2θc4≥0.015.
