Abstract
The problem that one embodiment of this invention aims to solve is to provide an energy storage element and a method for manufacturing the same, as well as an energy storage device and a method for manufacturing the same, which can improve the degree of design freedom for implementation. [Solution] According to one embodiment of the present invention, the energy storage element comprises a laminate in which a strip-shaped first electrode member and a strip-shaped second electrode member are stacked, and which has a first region and a second region different from the first region. The laminate has a first winding portion in which the first region is wound around a first winding axis, and a second winding portion in which the second region is wound around a second winding axis different from the first winding axis.
