Abstract
A nonaqueous electrolyte air battery has s positive electrode comprises at least a catalyst which activates oxygen, a conductive material and a binder, when a thermal decomposition starting temperature of the binder is T1° C. and a thermal decomposition ending temperature of the binder is T2° C. A signal with any of mass numbers of 81, 100, 132 and 200 is present in pyrolysis mass spectrometry of the binder in a range of T1° C. to T2° C. Where a peak area at T1° C. is X and a peak area at T2° C. is Y, the X and Y satisfy a relation of 2X≧Y.
