A problem with conventional air batteries is that they cannot be directly connected to each other due to their structure, and they cannot therefore be used for on-vehicle power sources. An air battery A1 includes: a cathode layer 2 and an anode layer 3 sandwiching an electrolyte layer 1; and an electrically insulative outer case 4 surrounding the peripheries of the electrolyte layer 1 and the cathode layer 2, wherein the cathode layer 2 comprises a cathode member 21, a cathode current collector 22 and a liquid tight/ gas permeable member 23, the anode layer 3 comprises an anode member 31 and an anode current collector 32, the cathode layer 2 is provided with a contact member 5 between the outer case 4 and the cathode layer 2, in which the inner end thereof is in contact with the periphery of the cathode current collector 22, and the outer end thereof is exposed on a cathode-side surface, and the outer end of the contact member 5 protrudes outward with respect to a surface of the liquid tight/ gas permeable member 23 to an extent reaching at least a plane including an end face of the outer case 4. Therefore, this air battery A1 can be directly connected to another battery A1 in series, and is suitable for an on-vehicle power source. |
