Abstract
Disclosed is a solid electrolyte battery including: a first electrode including a first collector, and a first active material layer formed on one surface of the first collector with an outer peripheral edge portion of the first collector remaining as a collector exposed portion; a second electrode including a second collector and second active material layers formed on both surfaces of the second collector; and a solid electrolyte interposed between the first electrode and the second electrode; wherein the second electrode is held in the first electrode in such a manner that the first active material layer is opposed to each of the second active material layers via the solid electrolyte, and is sealed in the first electrode by joining the collector exposed portion of the first electrode to each other. This battery is allowed to be further thinned and reduced in weight, to be improved in energy density per weight and energy density per volume, and to be enhanced in air-tightness.
