Abstract
A power storage device includes power storage cells and a bus bar. Each power storage cell includes positive-electrode sheets, negative-electrode sheets, a positive-electrode current collector plate, a negative-electrode current collector plate, and a laminated film. The positive-electrode current collector plate includes a positive-electrode protrusion shaped to protrude from the laminated film, and the negative-electrode current collector plate includes a negative-electrode protrusion shaped to protrude from the laminated film. The power storage cells are stacked such that the positive electrode protrusion in one power storage cell and the negative-electrode protrusion in another power storage cell adjacent to the one power storage cell face each other in the one direction. The bus bar is shaped to extend in the one direction and connects the positive-electrode protrusion to the negative-electrode protrusion.
