A main object of the present invention is to provide an air secondary battery that can lower a charging voltage in an air secondary battery using a nonaqueous liquid electrolyte. The object is attained by providing an air secondary battery comprising: an air cathode having an air cathode layer containing a conductive material and an air cathode current collector that collects a current of the air cathode layer, an anode having an anode layer containing an anode active material and an anode current collector that collects a current of the anode layer and a nonaqueous liquid electrolyte that conducts a metal ion between the air cathode layer and the anode layer; wherein the air cathode current collector is formed of a carbon material and the nonaqueous liquid electrolyte contains a sulfonimide salt.
