A positive electrode for a metal-air battery, the positive electrode including: a first layer disposed on a surface of an electrolyte membrane or a separator and including a first carbon material, a first electrolyte, and a first binder having an affinity with the first electrolyte; and a second layer disposed on the first layer and including a second carbon material, a second electrolyte, and a second binder having an affinity with the second electrolyte, wherein the first carbon material is different from the second carbon material, the first carbon material has a Brunauer Emmett Teller specific surface area which is greater than a Brunauer Emmett Teller specific surface area of the second carbon material, and wherein an amount of the first binder may be about 1.5 times to about 3 times greater than an amount of the second binder.
