PROBLEM TO BE SOLVED: To provide a negative electrode body of an all-solid-state battery in which blockage or fracture of an Li ion conduction path due to expansion and contraction of a negative electrode active material can be suppressed.SOLUTION: In a negative electrode body for an all-solid-state battery having a negative electrode collector and a negative electrode active material layer formed on the negative electrode collector and containing a negative electrode active material and a solid electrolyte material, the negative electrode active material layer contains a negative electrode active material mixing a carbon-based active material and a metal-based active material. The metal-based active material is an active material causing alloying reaction on Li, and the content of the metal-based active material increases from the surface side not having the negative electrode collector to the negative electrode collector side in the thickness direction of the negative electrode active material layer. |
