Abstract: A battery of the present disclosure includes a positive electrode, a negative electrode, and a solid electrolyte layer. The solid electrolyte layer is positioned between the positive electrode and the negative electrode. The solid electrolyte layer includes a solid electrolyte having lithium-ion conductivity. The negative electrode includes: a negative electrode current collector; and a negative electrode active material layer positioned between the negative electrode current collector and the solid electrolyte layer. The negative electrode active material layer has a plurality of columnar particles and is substantially free of an electrolyte. The columnar particles include silicon as a main component.
