Abstract
A power storage device includes: a module stacked body including at least one power storage module including a plurality of stacked electrodes; and a housing constituting a first sealed space for accommodating the module stacked body, wherein the housing has a housing body including a cylindrical side wall extending along a stacking direction in the module stacked body and a plate-shaped bottom wall closing one end of the side wall and a lid being joined to the other end of the side wall and constrains the module stacked body in the stacking direction of the electrode inside the first sealed space by deforming at least a portion of the bottom wall and the lid so as to come close to each other due to an air pressure difference between the inside and outside of the first sealed space.
