NOVELTY - An all-solid-state battery (10) has an active material (4), an electrode active material layer containing a solid electrolyte material (5) which is single-phase electronic-ion mixed conductor with which active material is contacted and having an anion component which is different from anion component of active material, and a solid electrolyte material (6) which is ion conductor which does not have electroconductivity. The solid electrolyte material (5) contains lithium-zirconium-sulfur alloy (Li2ZrS3) having peak of 34.2 plus minus 0.5 degrees in X-ray-diffraction measurement using copper K alpha -ray.    USE - All-solid-state battery. Uses include but are not limited to personal computer, video camera, mobile telephone, electric vehicle and hybrid vehicle.    ADVANTAGE - The all-solid-state battery has favorable electroconductivity and suppressed increase in resistance in interface of active material and solid electrolyte material.    DETAILED DESCRIPTION - An all-solid-state battery has an active material, an electrode active material layer containing a solid electrolyte material (5) which is single-phase electronic-ion mixed conductor with which active material is contacted and having an anion component which is different from anion component of active material, and a solid electrolyte material (6) which is ion conductor which does not have electroconductivity. The solid electrolyte material (5) contains lithium-zirconium-sulfur alloy (Li2ZrS3) having peak of 34.2 plus minus 0.5 degrees in X-ray-diffraction measurement using copper K alpha -ray. The ratio of diffraction intensity of peak of zirconia of 31.4 plus minus 0.5 degrees C and diffraction intensity of peak of lithium-zirconium-sulfur alloy (Li2ZrS3) of 34.2 plus minus 0.5 degrees is 0.1 or less. An INDEPENDENT CLAIM is included for manufacture of all-solid-state battery.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the all-solid-state battery.
