Abstract
An electrode body has a current collector, and an electrode layer that is formed on the current collector and that has an electrode active material and a conductive material. The concentration of the conductive material at a current collector-side surface of the electrode layer is lower than the concentration of the conductive material at an opposite-side surface that is opposite from the current collector-side surface.
