Abstract: A capacitor is disposed on a substrate that is insulative. An inductor is disposed on the substrate. The inductor includes a conductor pattern having at least one end connected to the capacitor. The capacitor includes a dielectric film that mainly contains the same constituent element as a constituent element mainly contained in the substrate and at least two electrodes that face each other with the dielectric film interposed therebetween.

Abstract: A passive component includes a substrate having insulating properties and having a surface having a recess, a bottom electrode filling at least a portion of the recess, a dielectric film provided on a surface of the bottom electrode, and a top electrode opposite to the bottom electrode with the dielectric film interposed therebetween. In a height direction perpendicular to the surface of the substrate, a dimension of the bottom electrode is larger than a dimension of the dielectric film.
