Abstract
A filter device includes: a multilayer board including a first dielectric layer, a first wiring layer including a reference electrode to which a reference potential is supplied, and a second dielectric layer positioned between the first dielectric layer and the first wiring layer and having a thickness different from a thickness of the first dielectric layer; a series passive element provided on a series wire electrically connecting a first terminal and a second terminal together; a first parallel wire electrically connecting the series wire and the reference electrode together; and a first parallel passive element provided on the first parallel wire. The first parallel wire includes: a first via penetrating through the first dielectric layer and electrically connected to the first parallel passive element; and a second via penetrating through the second dielectric layer and electrically connecting the first via and the reference electrode together.
