  "textContent": "According to an aspect of the present invention, provided is a sulfide solid-state battery including a negative electrode current collector that contains copper, and a negative electrode mixture layer that contains a negative electrode active material, a sulfide solid electrolyte material, and an oxide solid electrolyte material. Assuming that the negative electrode mixture layer is virtually divided into two portions in a thickness direction, the upper layer portion contains a larger amount of the sulfide solid electrolyte material than the lower layer portion, and the lower layer portion contains a larger amount of the oxide solid electrolyte material than the upper layer portion.",
