Provided are an all-solid-state battery having excellent output performance and an all-solid-state battery negative electrode that can constitute the all-solid-state battery. An all-solid-state battery negative electrode according to the present invention is characterized by: having a molded body of a negative electrode mixture containing a negative-electrode active material, a solid electrolyte, and a conduction promoter; and containing, as the negative-electrode active material, particles of lithium titanium oxide in which the ratio Dp/D50 is larger than 0.6, where Dp is the primary particle diameter and D50 is the particle diameter, and the specific surface area is 2 m2/g or more. In addition, an all-solid-state battery according to the present invention is characterized by: having a positive electrode, a negative electrode, and a solid electrolyte layer interposed between the positive electrode and the negative electrode; and having the all-solid-state battery negative electrode according to the present invention as the negative electrode. |
