Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery which reduces or resolves the deterioration of a positive electrode due to heat generated when separators are heat welded.SOLUTION: A battery includes: a bagged positive electrode where a bag is formed by joining at least parts of end parts of separators 60 through heat welding and placing a positive electrode 50 in the bag; and a negative electrode 30 which is laminated on the bagged positive electrode and is larger than the positive electrode 50. Welded parts 62, formed in the separators 60 by heat welding, are provided at the outer side of an outer periphery of the negative electrode 30 when viewed in the lamination direction.
