Abstract
As a method of manufacturing a metal-air battery, a first step is included of stacking an exterior body (e.g., first resin film), a water-repellent film (), and a positive electrode (e.g., air electrode) in the stated order. The first step includes: a fusing step of fusing the exterior body and the water-repellent film (); and a compression step of compressing the water-repellent film () and the positive electrode. The fusing step fuses the exterior body and the water-repellent film (). After the first step, a portion of the exterior body is removed from inside the fusing portion () formed in the fusing step, to form an opening (e.g., air inlet) in the exterior body.
