Abstract
A filter device includes an inductor component, and a substrate on which the inductor component is mounted, the substrate including a first dielectric layer having a mounting surface, a first pad electrode, which is provided on the mounting surface and to which a first terminal of the inductor component is connected, and a first electrode, which is connected and is provided such that the first dielectric layer is positioned between the first electrode and the first pad electrode. At least part of the first electrode overlaps the first pad electrode when the mounting surface is viewed in a plan view. The first pad electrode and the at least part of the first electrode form a first capacitor.
