Abstract
The electricity storage cell is an electricity storage cell in which battery elements are accommodated inside a cell can and an opening portion on the top of the cell can is sealed by an opening sealing body; inside the cell can, there is an expansion force absorber which is capable of absorbing expansion force of the battery elements by receiving expansion of the battery elements and compressing; the battery elements are disposed between the expansion force absorber and an inner wall surface of the cell can; and the expansion force absorber has a height corresponding to the height of the battery elements, and has a lower rigidity on the opening sealing body side than in a central portion of the height direction of the cell can, or has a smaller thickness on the opening sealing body side than in the central portion of the height direction of the cell can.
