Abstract
An electrode-foil includes a foil having a metal layer on the surface thereof, a first dielectric film formed on the metal layer, and a second dielectric film formed on the first dielectric film. The first dielectric film is composed of a metal oxide of a metal constituting the metal layer. The thickness of the first dielectric film is greater than 0 nm and less than 10 nm. The second dielectric film is predominantly composed of a metal compound different from the metal oxide of the first dielectric film.
