1. An air battery using oxygen in air as a cathode active material, the air battery comprising:
a cylindrical anode made of a metal;
a cathode constituted by a co-continuous body having a three dimensional network structure formed by an integrated plurality of nanostructures having branches;
a separator that is arranged between the cathode and the anode and absorbs an electrolytic solution; and
a cylindrical housing arranged outside the anode, wherein
the cathode is arranged inside the anode via the separator,
the anode has an open hole reaching the separator and constitutes a housing of the air battery, and
the cylindrical housing has an open hole connected to the open hole of the anode.
