Abstract
A filter includes a multilayer body in which a plurality of dielectric layers and a plurality of conductor layers are alternately stacked in a stack direction, an inductor including a first conductor pattern formed of at least one of the plurality of conductor layers, and a second conductor pattern provided in the multilayer body, the second conductor pattern being not connected to other conductors in the multilayer body, X≤7.5×107/(fc×√{square root over (εr)}) being satisfied where a maximum width of the second conductor pattern is X (m), a frequency at a high-frequency end of a passband is fc (Hz), and a relative permittivity of the plurality of dielectric layers is εr.
