Abstract
An LC filter circuit includes first and second LC-trap capacitor conductors, respectively, that are opposed to third and LC-trap capacitor conductors with an insulating sheet therebetween to define first and second LC trap capacitors, respctively. A portion of a first LC resonator inductor and the first LC trap capacitor define an input-side LC trap circuit, and a portion of a second LC resonator inductor and the second LC trap capacitor define an output-side LC trap circuit.
