Abstract:
A monolithic LC resonator comprising:a laminated body including a plurality of insulation layers, an inductor pattern, and a capacitor pattern laminated together; an LC resonance circuit in the laminated body, which includes an inductor defined by the inductor pattern, and a capacitor defined such that the capacitor pattern is opposed to the inductor pattern with one of the plurality of insulation layers being sandwiched between the capacitor pattern and the inductor pattern; wherein said inductor of the LC resonance circuit has a tubular structure including at least two via-holes and at least two inductor patterns which are electrically connected to each other through said at least two via-holes, the at least two via-holes extending along a length of said inductor pattern, and the capacitor pattern is located inside of the tubular structure of said inductor.
