1. A negative electrode for an all-solid-state battery to be used in an all-solid-state battery, the negative electrode comprising
a molded body made of a negative-electrode mixture that contains a negative-electrode active material, a solid electrolyte, and a conductive assistant,
wherein lithium titanium oxide particles in which a ratio Dp/D50 of a primary particle diameter Dp to a particle diameter D50 is greater than 0.6 and a specific surface area is 2 m2/g or more are contained as the negative-electrode active material.
