PROBLEM TO BE SOLVED: To provide an electricity storage element including a spacer which can be easily disposed on a curved surface of an electrode body so as to prevent the electrode body from being damaged, in an electricity storage element including a spacer between a container and an electrode body.SOLUTION: An electricity storage element comprises: an electrode body 120 formed by laminating a positive electrode, a negative electrode and a separator; a container 100 containing the electrode body 120; and a bottom face spacer 170 disposed between the electrode body 120 and the container 100. The bottom face spacer 170 includes a support 173 supporting the electrode body 120, and holding parts 174, 175 disposed at both ends of the support 173 and sandwiching both side faces of the electrode body 120, and has a groove 176 as a fragile part, at the support 173 and/or the holding parts 174, 175. |
