Abstract
A capacitor electrode and manufacturing method capable of not only storing electric charge but also being charged by a chemical reaction of an active material to improve energy density by increasing a storage capacity and firmly holding a sufficient amount of active material while eliminating the necessity of adhesive. A capacitor electrode capable of storing electric charge on its surface to be charged as a result of application of voltage has a substrate () made of an electrically conductive metal. Also, it has a carbon film (), made up of a coating of carbon material, formed on a surface of the substrate (). Additionally, nanoparticles (), made of a metal or an oxide of the metal, are included in the carbon film ().
