    • A circuit substrate comprises a lamination of plural resin insulation films and includes, on a surface and in an interior of the circuit substrate, plural interconnection layers. One of the plural resin insulation films is formed on a first conductor pattern constituting one of the plural interconnection layers in such a manner that a bottom principal surface of the resin insulation film makes a contact with a surface of the first conductor pattern, the resin insulation film including an opening defined by a sloped surface and exposing the first conductor pattern at the bottom principal surface. A ceramic high-K dielectric film is formed at a bottom of the opening in contact with the surface of the first conductor pattern, wherein there is formed a second conductor pattern constituting one of the plural interconnection layers on the resin insulation film so as to cover the sloped surface and in contact with a surface of the ceramic high-K dielectric film.
