Abstract: Provided is a secondary battery suitable for a portable information terminal or a wearable device, or an electronic device having a novel structure with a variety of forms and a secondary battery that fits the form of the electronic device. The secondary battery is sealed using a film having projections that can reduce stress on the film caused when external force is applied. The film has a pattern of projections formed by pressing (e.g., embossing). A top portion of each of the projections has a region thicker than a bottom portion of each of the projections. The thickness of the top portion of each of the projections is 1.5 or more times, preferably 2 or more times, as large as that of the bottom portion of each of the projections, and is a thickness such that each of the projections has a convex space.

Abstract: An electricity storage device includes an electrode assembly having primary electrodes and secondary electrodes, a case having a wall with an inlet, and an insulator. The electrode assembly has a facing surface facing the wall of the case. The primary electrodes have primary tabs protruding from one edge. The second electrodes have secondary tabs. The group of primary tabs and the group of secondary tabs each have a first side and a second side on the opposite sides. In each of the group of primary tabs and the group of secondary tabs, the first side faces the facing surface, and the second side is bent to face the wall of the case. The inlet is located at a position sandwiched regions of the wall onto which the primary tab group and the secondary tab group are projected when the wall is viewed from a direction perpendicular to the facing surface.
