Abstract
The present invention relates to a dry electrode including a current collector; and an electrode material mixture film disposed on the current collector, wherein the electrode material mixture film includes an electrode active material and a fibrillizable binder, wherein a ratio (I<sub>B</sub>/I<sub>A</sub>) of a C<sub>3</sub>H<sub>7</sub><sup>+</sup> peak intensity (I<sub>B</sub>) to a C<sub>2</sub>H<sub>3</sub>O<sup>+</sup> peak intensity (I<sub>A</sub>), which is measured on a surface of the current collector by Time-of-Flight secondary ion mass spectrometry (ToF-SIMS), is 1.3 or less, and a ratio of a carbon content at an interface of the current collector to a carbon content in the electrode material mixture film, which is measured by scanning electron microscope-energy dispersive X-ray spectroscopy, is 1.03 or less.
