PROBLEM TO BE SOLVED: To provide an electricity storage device capable of reducing the flow of an electrolyte within an electrical cell.SOLUTION: An electricity storage device includes a plurality of electrical cells, a plurality of cooling plates and a binding member. Each electrical cell includes a wounded body serving as a power generation element, inside thereof. Each cooling plate is alternately disposed with each electrical cell, and has a plurality of projecting parts, the longitudinal direction of which is orthogonal to the winding axis of the wounded body, on the surface. The projecting parts are aligned in the winding axial direction on the surface of each cooling plate. The rigidity of a part of the projecting part of each cooling plate is lower than that of other parts of the projecting part. |
