Abstract
An electrode includes a composite mixture layer formed by applying a composite mixture having one of a cathode active material or an anode active material on one of main surfaces of a plurality of current collectors formed in substantially rectangular shapes; and a non-applied part to which the composite mixture is not applied at both end parts in the longitudinal direction. One current collector is connected to the other adjacent current collector at one end side in the longitudinal direction through a connecting part to which the composite mixture is not applied and which is provided continuously to the non-applied parts. In the electrode constructed as described above, a plurality of current collectors can be laminated to obtain a multi-layer structure and an electric current can be collected from a lead welded to only one end part of the current collector. Thus, the electrode of a new form having an excellent productivity and a high capacity can be provided.
