Abstract: A capacitor electrode includes a substrate having electrical conductivity, a conductive layer formed on a surface of the substrate, and an electrode layer formed on the conductive layer. The electrode layer is allowed to adsorb and desorb ions on a surface thereof. The conductive layer contains flake graphite. A density of the conductive layer is greater than 1.1 g/cm3. An average particle size D50 of the flake graphite, which is measured by using a dynamic light scattering method, is less than or equal to 10 μm.
