1. A metal-air cell, comprising:
a negative electrode;
a positive electrode; and
an outer pouch housing the negative electrode and the positive electrode,
wherein:
at least one of the negative electrode and the positive electrode includes a lead extending outside from an inside of the outer pouch,
the lead includes a sealing member provided to an outer face of the lead,
the outer pouch includes a fusing portion in which the sealing member and the lead are held and fused together, the fusing portion sealing the outer pouch,
the sealing member including:
an adhesive layer covering the lead inside the outer pouch, and
a resin film layer fused with the outer pouch,
the resin film layer is directly in contact with the lead, and
the adhesive layer is externally provided across the resin film layer and the lead and coats an interface between the resin film layer and the lead at an end of the resin film layer located inside the outer pouch so that the interface between the resin film layer and the lead is kept from being exposed to an electrolytic solution inside the outer pouch.
