ABSTRACT:
One pair of resonant electrodes is formed in a loop shape or a spiral shape in a substrate stacking direction symmetrically to each other. This allows a longitudinal space in substrate to be reduced. A first capacitor having an electrode connected to the grounding conductor layer, an electrode connected to an open-end side of the resonant electrode, and a dielectric layer is provided. A second capacitor having an electrode connected to the grounding conductor layer, an electrode connected to an open-end side of the resonant electrode, and a dielectric layer is also provided. This results in having a desired characteristic even if a length of the resonant electrode is short.
