Abstract
The power storage device includes a power storage module and a conductive plate. The power storage module includes an electrode laminate including current collectors stacked on each other in a first direction. At least one of the positive electrode terminal electrode, the negative electrode terminal electrode, and the bipolar electrode includes an active material layer including grooves arranged in a second direction orthogonal to the first direction, and the grooves extend in a third direction crossing the second direction. The conductive plate includes an outer surface including depressions depressed in the first direction and extending in the second direction, the current collector arranged at the stack end of the electrode laminate includes an exposed face in contact with the outer surface, the exposed surface includes protrusions overlapping the active material layer in the first direction, and the protrusions protrude in the first direction and extend in the third direction.
