Abstract
An electronic component having: a substrate, a lower conductor layer provided on the substrate; an inorganic dielectric film that covers the lower conductor layer; and an upper conductor layer having an upper electrode portion provided on the inorganic dielectric film. The lower conductor layer has a lower electrode portion that together with the upper electrode portion and the inorganic dielectric film constitutes a capacitor, and a coil portion that constitutes an inductor. The entire inorganic dielectric film is formed integrally, and the lower conductor layer is in contact only with the substrate, inorganic dielectric film, and upper conductor layer.
