Abstract
A monolithic LC resonator includes insulation sheets and inductor patterns that are electrically connected through long via-holes formed in the insulation sheets. The long via-holes are arranged along the right edge and left edge of the inductor patterns, respectively. The inductor patterns and the long via-holes define an inductor having a tubular structure with a substantially rectangular cross-section and filled with an insulator therein. A capacitor pattern is opposed to the open ends of the inductor patterns through the sheets, respectively, to define a capacitor. That is, the capacitor pattern is laminated inside of the tubular structure of the inductor. The capacitor and the inductor having the tubular structure define an LC parallel resonance circuit.
