Abstract
Disclosed herein is an electrode for a secondary battery including an electrode mixture layer including an electrode active material on one surface or both surfaces of a current collector, wherein the electrode mixture layer includes a plurality of fine holes recessed toward the current collector from a vertical cross-sectional surface, and each of the fine holes is a horn-shaped hole whose diameter is gradually decreased from the vertical cross-sectional surface toward the current collector in the electrode mixture layer.
