PROBLEM TO BE SOLVED: To provide a metal-air battery capable of achieving further reduced size, reduced weight and reduced cost.SOLUTION: A metal-air battery includes a positive electrode layer, a negative electrode layer and an electrolyte layer arranged between the positive electrode layer and the negative electrode layer. In the metal-air battery, a proportion of an area of a surface of the positive electrode layer on a side facing the electrolyte layer relative to an area of a surface of the electrolyte layer on a side facing the positive electrode layer is 20-95%. |
