1. A metal-air cell comprising:
a negative electrode;
a negative electrode case housing the negative electrode and sealed while a lead of the negative electrode extends from the negative electrode case, the negative electrode case comprising a separator that forms at least part of the negative electrode case;
an air electrode facing the negative electrode across the separator; and
a cell case housing the negative electrode case and the air electrode and sealed while the lead of the negative electrode extends from the cell case and a lead of the air electrode extends from the cell case; wherein
the negative electrode case further comprises a first container comprising a thermoplastic resin material,
the first container houses the negative electrode, is sealed while the lead of the negative electrode extends from the first container, and defines a first opening, and
the separator covers the first opening.
