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 translation: 目的是提供一种适用于可穿戴装置的二次电池。 另一个目的是提供一种新颖的蓄电装置。 用于二次电池的电极的一部分，特别是集电器和活性材料层，经受切割加工以形成复杂的形状。 由于电极远离曲率中心的弯曲程度比接近曲率中心的电极的弯曲程度大，所以抑制了电极端部远离曲率中心的电极靠近曲率中心的位置偏移 或者减轻施加到远离曲率中心的电极的张力。
