Abstract
A secondary battery suitable for a portable information terminal or a wearable device is provided. An electronic device having a novel structure which can have various forms and a secondary battery that fits the forms of the electronic device are provided. In the secondary battery, sealing is performed using a film provided with depressions or projections that ease stress on the film due to application of external force. A pattern of depressions or projections is formed on the film by pressing, e.g., embossing.
