Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problems of self corrosion, polarization, etc. to provide a metal air battery and a metal air fuel battery which are superior in battery performances of an energy density, voltage, etc. long in life and high in safety.SOLUTION: A metal air battery and a metal air fuel battery each comprise: a negative electrode including magnesium (Mg), amphoteric metal and an alloy thereof as an active material; a positive electrode (air electrode) including oxygen as an active material; and a neutral aqueous electrolyte. The electrolyte is arranged by dissolving a polymer fatty acid salt in a neutral aqueous electrolyte.SELECTED DRAWING: Figure 2 【課題】自己腐食や分極等の問題を解決し、エネルギー密度や電圧等の電池性能に優れ、寿命が長く、安全性の高い金属空気電池及び金属空気燃料電池を提供することを目的とする。【解決手段】マグネシウム（Ｍｇ）、両性金属、及び、これらの合金を活物質とする負極と、酸素を活物質とする正極（空気極）と、中性水系電解質とからなる金属空気電池及び金属空気燃料電池において、電解質が中性水系電解質に高分子肪酸塩を溶解したものであることを特徴とする。【選択図】図２
