Method for fabricating secondary battery

A method for fabricating a secondary battery, comprising:

• 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 to surround the first electrode, the separator, and the second electrode in a frame-like manner;
• impregnating at least one of the first electrode, the separator, and the second electrode with the electrolyte and 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,
• wherein one of the first electrode and the second electrode is a positive electrode, and the other is a negative electrode, and
• wherein an area of the resin layer irradiated with the ultraviolet light during the sealing is larger than an area of the resin layer irradiated with the ultraviolet light under the reduced pressure.
