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.

Abstract: A capacitor electrode includes a conductive base member and an electrode part electrically connected to the base member. The electrode part contains carbon particles of a first carbon material capable of adsorbing and desorbing ions. The electrode part further contains voids including first voids with diameters of not less than 0.2 μm and not more than 1.0 μm, and second voids with diameters of not less than 0.05 μm and less than 0.2 μm. The value of (VA×VA)/(VB×M) is greater than 0.022, where VA is the sum of the volumes of the first voids, VB is the sum of the volumes of the second voids, and M is the volume of the electrode part per unit weight of the electrode part.
