Abstract
An electrode disclosed here includes a surface part of an electrode active material layer has a plurality of first grooves extending in a width direction of the electrode current collector and at least one second groove extending in a longitudinal direction of an electrode current collector. The first groove is formed to be continuous from one end to another end. Here, a region in which the first groove and the second groove are formed is uniformly divided into three layers, which are an upper layer, an intermediate layer and a lower layer, in a thickness direction from the surface of the electrode active material layer to the electrode current collector, and when electrode densities (g/cm) of the upper layer, the intermediate layer and the lower layer of the groove are d, d, and d, respectively, a relationship of 0.8<(d/d)<1.1 is satisfied.
