An electrode of the present disclosure includes an electrode mixture layer and an electrode current collector layer. The electrode current collector layer is in contact with the electrode mixture layer. The electrode mixture layer includes a solid electrolyte material and an active material. The solid electrolyte material includes Li, M, and X. M is at least one selected from the group consisting of metal elements other than Li and metalloid elements. X is at least one selected from the group consisting of F, Cl, Br, and I. The electrode current collector layer has a surface material in contact with the electrode mixture layer, and an iron content in the surface material is 50 mass % or less.
