Abstract
Provided are a stacked resonator capable of achieving miniaturization and minimum loss, and a stacked resonator capable of suppressing any unnecessary resonance mode due to interdigital-coupling. The stacked resonator includes a first conductor group having a plurality of conductor lines in a stacking arrangement, and a second conductor group having a plurality of other conductor lines in a stacking arrangement so as to be alternately provided opposing to the conductor lines in the first conductor group, thereby establishing an interdigital-coupling together with the first conductor group.
