PURPOSE:To lengthen the life of battery by preventing the short-circuit, etc., of electrode plate by integrally forming a synthetic resin frame body with an uneven inside surface and a current collector. CONSTITUTION:An active substance is filled in the acid-resistant synthetic resin frame body 6 with the uneven inside surface 5, and then the current collector is pressed with the frame body 6 to one body. Because the active substance is held by the uneven inside surface, the exfoliation of the active substance can be prevented and also short-circuit in the sides and bottom of the electrode plate can be suppressed. Thus, the life of the battery can be lengthened. |
