A multilayer filter includes a plurality of mutually coupled resonant circuits provided within a multilayer body. Capacitor internal electrodes, inductor internal electrodes, and inductor via electrodes, ground via electrodes, and input-output via electrodes are arranged within the multilayer body. The ground via electrodes and the input-output via electrodes are provided on a dielectric layer on a mounting surface, or a second dielectric layer on a first dielectric layer provided on the mounting surface. The capacitor internal electrodes arranged towards the side of the mounting surface do not overlap the input-output electrodes when viewed in plan view. With this configuration, degradation in frequency characteristics of a resonant circuit is effectively prevented by controlling one of an inductive component and a capacitive component of the resonant circuit.
