PROBLEM TO BE SOLVED: To provide a clad type positive electrode plate capable of improving capacity density. SOLUTION: A plurality of clad tubes 2A are arrayed like a flat plate and rod type current collectors are respectively arranged at the center of the clad tubes 2A. The clad tubes 2A are filled with an active material so as to envelope current collectors. Also, each clad tube 2A is kept in contact via adjacent surface. As the adjacent surface of a plurality of clad tubes 2A are kept in contact with each other, the appearance of a V-groove type gap on both principal planes of an electrode plate can be restrained, thereby improving the capacity density of the clad type positive electrode plate. |
