A laminated battery disclosed herein includes an electrode body, a laminated exterior body, and positive and negative electrode terminals. At least one of the positive and negative electrode terminals is configured of a plate-shaped clad material in which a first metal and a second metal, which are different from each other, are joined to each other, and a tab film composed of a resin material is arranged on the surfaces of the first metal and the second metal of the clad material. The boundary region of the first metal and the second metal of the clad material is not exposed to the outside of the exterior body, and the tab film is arranged at a peripheral edge portion close to the boundary region, excluding the boundary region, on the wide surface of the clad material, and the tab film is welded to the exterior body.
