Abstract
A filter includes a first resonator, a second resonator, and a third resonator provided between the first resonator and the second resonator in a circuit configuration, and the third resonator includes a first resonator conductor layer. A plurality of columnar conductors of a shield of the filter include two specific first columnar conductors arranged at a first interval and two specific second columnar conductors arranged at a second interval. A stack includes a first dielectric part located between the two specific first columnar conductors and a second dielectric part located between the two specific second columnar conductors. At least one of a first line part and a second line part of the first resonator conductor layer is arranged at a position closer to the second dielectric part than the first dielectric part.
