摘要： An electrode body in which current collecting bodies are welded to upper and lower end surfaces of a spiral electrode group formed by interposing a separator between a positive electrode plate and a negative electrode plate is installed into a battery case. After the current collecting body is welded to the battery case, the cylindrical body is loaded on the diameter of the current collecting body, then the blade portions are welded, then the electrolytic solution is injected, and then a pair of electrodes are arranged on the port-sealing body and the battery case while bringing the bottom surface of the port-sealing body into contact with the peripheral side surface of the cylindrical body. After the contact portion between the port-sealing body and the peripheral side surface of the cylindrical body is welded by supplying the current in the discharge direction while applying pressure between the electrodes, the opening of the battery is sealed by caulking the opening edge of the battery case, and then the port-sealing body is pushed into the battery case by applying the force to the port-sealing body, whereby the storage battery is fabricated.
