Abstract
The power storage device is provided with a cell stack body formed by alternately arranging a plurality of secondary cells and a plurality of buffer plates. Each of the buffer plates has a non-deformable section and a deformable section that is elastically deformed according to a volume change in the secondary cell. The non-deformable section has a through hole in which the deformable section is fitted. The deformable section is formed thicker than the non-deformable section.
