Abstract
Provided is a high-density electrode and a method of manufacturing the same. An electrode for a secondary battery includes an electrode current collector, and an electrode active material layer formed on at least one surface of the electrode current collector. The electrode active material layer includes an H1 region, an H2 region and an H3 region sequentially provided from an end of the electrode active material layer toward a center. The H2 region includes an inclined section in which a thickness increases from the H1 region toward the H3 region, and the electrode satisfies the following formulas (1) and (2), 0.2≤h1/h2≤0.7 . . . (1), h2/h3≥0.9 . . . (2), where h1 is an average thickness of the H1 region, h2 is an average thickness of the H2 region, and h3 is an average thickness of the H3 region.
