    • This invention provides a negative electrode and a non-aqueous electrolyte secondary battery including the negative electrode. The negative electrode includes a Li-absorbing element as a negative electrode active material, is free from deformation, separation of the negative electrode active material layer from the negative electrode current collector, and deposition of lithium on the negative electrode current collector, and is excellent in cycle characteristic, large-current discharge characteristic, and low-temperature discharge characteristic.The negative electrode of this invention includes: a current collector having depressions and protrusions on a surface in the thickness direction thereof; and a negative electrode active material layer that includes a plurality of columns containing a negative electrode active material that absorbs and releases lithium ions, the columns being grown outwardly from the surface of the current collector. The negative electrode of this invention is characterized in that the columns are grown at an inclination angle relative to the direction perpendicular to the surface of the current collector, and that the inclination angle of the columns changes reversibly depending on absorption and release of lithium ions by the negative electrode active material.
