Abstract: Provided is a battery in which the internal resistance is further decreased. The present disclosure provides a battery, comprising a positive electrode, a negative electrode, and an electrolyte layer provided between the positive electrode and the negative electrode. The electrolyte layer includes a first solid electrolyte material. The first solid electrolyte material includes Li, M, and X, and does not include sulfur. M is at least one selected from the group consisting of metalloid elements and metal elements other than Li. X is at least one selected from the group consisting of Cl, Br, and I. The negative electrode includes a negative electrode active material and a sulfide solid electrolyte.
