Abstract
The electrodes disclosed herein, a low-density region having a relatively low electrode density and a high-density region having a relatively high electrode density are repeated on a surface of the electrode active material layer in a predetermined pattern at a constant pitch. The electrode active material layer is evenly divided into three layers of an upper layer, an intermediate layer, and a lower layer in a thickness direction from the surface of the active material layer to the electrode current collector, and when the electrode densities (g/cm) of the upper layer, the intermediate layer, and the lower layer of the low-density region are respectively d, d, and dand the electrode densities (g/cm) of the upper layer, the intermediate layer, and the lower layer of the high-density region are respectively d, d, and d, a relation of d/d<d/dis satisfied.
