摘要

A power storage element (10), provided with: an electrode body (400) having curved parts (431) and (432) obtained by winding an electrode; a container (100) housing the electrode body (400); and a lid plate structure (180) having a lid plate (110) for closing the container (100). The electrode body (400) is housed in the container (100) so that one end part in the winding axis direction faces the lid plate structure (180). The power storage element (10) has spacers (side spacers (700)) attached to the curved parts (431) and (432), one end part of the spacers being in contact with a part of the lid plate structure (180).
