Abstract: An object is to provide a secondary battery suitable for a wearable device. Another object is to provide a novel power storage device. Part of an electrode, specifically a current collector and an active material layer, for a secondary battery is subjected to cutting processing to have a complex shape. This suppresses the positional shift of an end portion of an electrode far from a curvature center from an electrode close to the curvature center due to the larger degree of bending of the electrode far from the curvature center than that of the electrode close to the curvature center, or relieves tension to be applied to the electrode far from the curvature center.

Abstract: An object is to provide an antifuse with little power consumption at the time of writing. The antifuse is used for a memory element in a read-only memory device. The antifuse includes a first conductive layer, a multilayer film of two or more layers in which an amorphous silicon film and an insulating film are alternately stacked over the first conductive layer, and a second conductive layer over the multilayer film. Voltage is applied between the first and second conductive layers and resistance of the multilayer film is decreased, whereby data is written to the memory element. When an insulating film having higher resistance than amorphous silicon is formed between the first and second conductive layers, current flowing through the antifuse at the time of writing is reduced.

Abstract: A power storage unit or the like which has flexibility is achieved. An exterior body has projections and depressions. For example, part of the exterior body has projections and depressions in a wave cross-sectional shape. The shape of the projections and depressions is not limited to a shape with a curve and may be a shape with a straight line, such as a rectangle wave shape or a triangle wave shape. The projections and depressions allows the exterior body to be easily shrunk on the inner side of a bend portion and easily stretched on the outer side of the bend portion.

Abstract: A novel multilayer film, a multilayer film suitable for an exterior material for a secondary battery, or a multilayer film that can be favorably used for a secondary battery suitable for a portable information terminal is provided. At least a metal layer and a resin layer are stacked as the multilayer film. A resin that constitutes the resin layer preferably has a durometer hardness of A90 or less, preferably A60 or less. Further, it is preferable that the resin be a material that does not break even when it is stretched to 150% of its original length, more preferably to 200% of its original length, in one direction. The thickness of the resin layer is preferably greater than or equal to 100 μm and less than or equal to 5 mm, more preferably greater than or equal to 500 μm and less than or equal to 3 mm.
