<P>PROBLEM TO BE SOLVED: To provide a compact bandpass filter that blocks external noise, and implements desired frequency characteristics by eliminating unintended electromagnetic field coupling between electrodes formed in the bandpass filter. <P>SOLUTION: A capacitor constituting a predetermined one of a plurality of LC resonators is arranged on one main surface side of a lamination direction of a laminate, and capacitors constituting the other LC resonators are arranged on the other main surface side of the lamination direction of the laminate. A capacitor electrode of the capacitor constituting the predetermined LC resonator is grounded. The grounded capacitor electrode is formed so as to cover at least the plurality of LC resonators when viewed in the lamination direction of the laminate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
