PROBLEM TO BE SOLVED: To enhance oxidizing resistance and mechanical strength by using a nickel-iron alloy containing the specified ratio of nickel as a core material of an air electrode of a zinc air battery comprising the positive electrode, a negative electrode, an electrolyte, and a separator. SOLUTION: A zinc air battery consists of a positive electrode, a negative electrode, an electrolyte, and a separator 6. A nickel-iron alloy containing at least 20% nickel is used in a core material of the air electrode 4 of the zinc air battery. An iron-nickel-chromium alloy in which at least the content of nickel is regulated to 20wt.% and the maximum content of chromium is regulated to 20wt.% is preferable to be used in the core material of the air electrode. |
