Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a secondary battery having an improved energy density, in which there is no resource problem nor risk of fire disaster and corrosion.SOLUTION: A metal-air battery includes a positive electrode 2 containing carbon graphite which oxidizes and reduces oxygen, a negative electrode 1 consisting of a metal electrode, an electrolyte layer 6 and a separator 7 interposed therebetween. Interior of the positive electrode 2 is composed of a positive electrode catalyst 13, and the outer surface is composed of a film 10 permeating oxygen in the air and a metal mesh 11. Inner surface of the negative electrode 1 composed of an aluminum or magnesium alloy, or the like, consists of a surface treatment film 12, and the electrolyte 6 contains an electrolyte additive 14 principally comprising a chloride of aluminum, magnesium, or the like.
