Abstract
At least part of a fabrication process of a secondary battery is automated. A highly reliable secondary battery is provided. The secondary battery is fabricated by placing a first electrode over a first exterior body; placing a separator over the first electrode; placing a second electrode over the separator; dripping an electrolyte on at least one of the first electrode, the separator, and the second electrode; placing a resin layer over the first exterior body; impregnating the at least one of the first electrode, the separator, and the second electrode with the electrolyte; then placing a second exterior body over the first exterior body to cover the first electrode, the separator, and the second electrode; curing at least part of the resin layer by irradiation of the resin layer with ultraviolet light under reduced pressure; and sealing the first electrode, the separator, and the second electrode with the first exterior body and the second exterior body under atmospheric pressure after the ultraviolet light irradiation.
