Abstract
A resonance inductor of a resonant circuit is formed of a chip inductor and an inductance fine adjustment pattern. A resonance capacitor is formed of a plurality of chip layered capacitors connected in parallel to each other via connection patterns formed on a substrate. The connection patterns are sequentially disconnected to adjust the capacitance of the resonance capacitor. Then, the inductance fine adjustment pattern is partially removed to adjust the inductance of the resonance inductor.
