PROBLEM TO BE SOLVED: To provide a long life metal-air battery which efficiently uses a negative electrode material.SOLUTION: A metal-air battery includes: a negative electrode 1 including at least a metal which may be ionized to be eluted in an electrolytic solution 2; a positive electrode 3 which is disposed so as to contact with the electrolytic solution 2; and a holding member including a conductive part which contacts with the negative electrode 1 to hold the negative electrode 1 at a position where the negative electrode 1 is not exposed from an interface between the electrolytic solution 2 and a gas phase.SELECTED DRAWING: Figure 1 |
