1. A resonator comprising:
a via electrode portion formed inside a dielectric substrate;
a plurality of shielding conductors formed on the dielectric substrate so as to surround the via electrode portion; and
a strip line connected to the via electrode portion inside the dielectric substrate and that faces at least the shielding conductor,
wherein a first input/output terminal or a second input/output terminal is coupled to the via electrode portion without involving the shielding conductors and the strip line.
