Disclosed is a battery pack in which a plurality of air batteries (A1) are stacked together. Each of the air batteries (A1) includes a cathode layer (2), an anode layer (3), an electrolyte layer (1) interposed between the cathode layer (2) and the anode layer (3) and a frame member (4) having electrical insulation properties and surrounding at least outer circumferences of the electrolyte layer (1) and the cathode layer (2). The cathode layer (2) includes a fluid-tight air-permeable member (32) located at a cathode surface thereof and having, when viewed in plan, an outer circumferential edge portion situated outside of the outer circumference of the electrolyte layer (1). The frame member (4) includes a holding portion (4A) located a cathode side thereof so as to hold the outer circumferential edge portion of the fluid-tight air-permeable member (23). The outer circumferential edge portion of the fluid-tight air-permeable member (23) is adapted as a compressed region (23A) to which a compressive load is applied in a thickness direction thereof. By this structure, it is possible to achieve both of thickness reduction and high electrolyte sealing performance. |
