Abstract
An energy storage device includes an electrode body in which an electrode is wound, a case that stores the electrode body, and spacers (side spacers) interposed between the case and the electrode body. The spacers each have an opening that exposes a portion of faces of curved portions of the electrode body from one end to the other end of the electrode body in a winding axis direction of the electrode body.
