PURPOSE:To feed a large current to a non-sintered cadmium negative electrode plate. CONSTITUTION:A portion 5b free from formation of an active substance layer is formed in a band shape when coating is applied to an electroconductive core, and the dia. B of a current feed roller facing this portion 5b is made greater than the dia. A of a current feed roller facing a part 5a where an active substance layer is formed. This enables the current feed roller to be in contact with both the portion 5b and the part 5a, so that current feeding can be made from both the surface of the part with active material layer and the core, which permits a large current to flow. |
