PURPOSE: An electrode is provided to maintain electrode performance after repeating charging and discharging by having high adhesion between a current collector and an electrode layer. CONSTITUTION: An electrode is that an electrode layer overlaps a current collector(101,201). In the overlapped region, the concentration of binder components is higher than that in the surface layer side region. In 1/4 point from the overlapped region, if the total thickness of the electrode layer, 20-40% peak intensity is shown within a specific wavelength. |
