Abstract
A thin film two terminal element comprises a lower metallic electrode disposed on an insulating substrate; an insulating film disposed on the insulating substrate and formed by a hard carbon film including at least one of amorphous and microcrystal properties with carbon and hydrogen atoms as a main structure forming element; and an upper metallic electrode disposed on the insulating substrate and formed by a metal having a standard free energy in the production of an oxide at a room temperature equal to or greater than that in the production of H.sub.2 O or CO.sub.2. The lower metallic electrode is disposed to partially overlap a transparent electrode and is formed by a metal having a standard electrode potential in an aqueous solution equal to or higher than that of the transparent electrode.
