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.
