PROBLEM TO BE SOLVED: To provide a power storage module which reduces contact resistance between terminals of adjoining cells, facilitates the rationalization of stock management and efficient productivity, and enhances workability when a module is assembled. SOLUTION: In a power storage module where an arbitrary number of power storage cells each having a positive electrode terminal and a negative electrode terminal in the shape of a flat protrusion are stacked and integrated while being stood in the vertical direction and connected in series in the horizontal direction, terminals of the positive electrode and negative electrode are projected reversely in the vertical direction, and tips thereof are bent reversely in the front and back direction in an L-shape. In two adjoining cells, the positive electrode of one cell and the negative electrode of the other cell are arranged to project in the same vertical direction, the tips of a pair of terminals projecting in the same direction are laminated on the bottom of the L-shape while facing each other and a screw member is screwed to the laminated portion. Consequently, the terminals of the positive electrode and the negative electrode are brought into pressure-contact with each other, and the power storage cells are integrated while being connected in series in the stacking order.
