Abstract:
1. A multilayer resonator comprising: a multilayer body defined by a laminate including a plurality of dielectric layers; first and second mounting surface electrodes defining a ground electrode or an input-output electrode and being provided on a mounting surface of the multilayer body, the mounting surface extending in a direction perpendicular or substantially perpendicular to a lamination direction of the plurality of dielectric layers; first and second capacitor internal electrodes provided on different ones of the plurality of dielectric layers and arranged to oppose each other in the lamination direction of the plurality of dielectric layers; an inductor internal electrode provided on only one of the plurality of dielectric layers that is different from the ones of the plurality of dielectric layers including the first and second capacitor internal electrodes provided thereon; a first inductor via electrode directly physically and electrically connected to the inductor internal electrode and the first capacitor internal electrode; a second inductor via electrode directly physically and electrically connected to the inductor internal electrode and the second capacitor internal electrode; a first mounting surface connection via electrode directly physically and electrically connected to the first capacitor internal electrode and to the first mounting surface electrode; and a second mounting surface connection via electrode directly physically and electrically connected to the second capacitor internal electrode and to the second mounting surface electrode; wherein the first capacitor internal electrode is located closer to the mounting surface than the second capacitor internal electrode and is arranged so that the first capacitor internal electrode does not overlap the second mounting surface electrode when viewed in the lamination direction of the plurality of dielectric layers; and the second capacitor internal electrode overlaps the first mounting surface electrode when viewed in the lamination direction of the plurality of dielectric layers.
