Abstract
In a battery casing a metal negative electrode that contains metal serving as a negative electrode active material and an air electrode are arranged so as to face each other in a state where at least a part of the metal negative electrode and the air electrode is immersed in an electrolytic solution inside a casing. The metal negative electrode is housed in a negative electrode housing in the casing. A separator separating the metal negative electrode and the air electrode is arranged at a side surface of the negative electrode housing. An opening through which inside of the negative electrode housing and outside of the negative electrode housing communicate with each other is provided on an upper surface of the negative electrode housing.
