Abstract

An object is especially to provide a metal-air battery that ensures a high output and continuance of the output over a long period of time as compared with a conventional one. A metal-air battery in the present invention includes a case, air electrodes disposed on both sides of the case, and a plurality of metal electrodes disposed inwardly separately from the air electrodes. The metal electrodes are opposed to one another via a space (S). The metal-air battery of the present invention can inhibit the reaction product from depositing between the air electrode and the metal electrode. A degree of freedom of a distance between the air electrode and the metal electrode is high. As described above, the high output and the continuance of the output over a long period of time are ensured.
