After the current collecting body (15) is welded to the battery case (20), the cylindrical body (20) is loaded on the diameter of the current collecting body (14), then the blade portions (22,22) are welded, then the electrolytic solution is injected, and then a pair of electrodes (W1,W2) are arranged on the port-sealing body (17) and the battery case (16) while bringing the bottom surface of the port-sealing body (17) into contact with the peripheral side surface of the cylindrical body (20). After the contact portion between the port-sealing body (17) and the peripheral side surface of the cylindrical body (20) is welded by supplying the current in the discharge direction while applying the pressure between the electrodes (W1,W2), the opening of the battery is sealed by caulking the opening edge of the battery case (16), and then the port-sealing body (17) is pushed into the battery case (16) by applying the force to the port-sealing body (17), whereby the storage battery is fabricated. <IMAGE> |
