Abstract
A power storage module including: a stacked body that includes electrodes stacked along a first direction; a sealing body that includes a first sealing portion joined to an edge portion of each of the electrodes, forms an inner space between the electrodes adjacent to each other, and seals the inner space; and an electrolytic solution that is stored in the inner space and includes an alkali solution. The electrodes include bipolar electrodes, and a negative terminal electrode. The power storage module includes surplus spaces different from the inner space on a route of an alkali creep phenomenon in which the electrolytic solution reaches the outside from the inner space through the negative terminal electrode.
