The lead film has a dented portion recessed in an inner direction of the battery case. The dented portion is opened toward outside of the battery case. The sealing portion located on a gas inlet portion of the dented portion has a recessed sealing portion recessed outward from an inner side of the battery case, and the recessed sealing portion does not overlap with a part of the gas inlet portion on a plane.",
