Abstract

A filter device includes a laminate body, plate electrodes, resonators, and shield conductors. The plate electrodes are provided in the laminate body and are spaced apart from each other in a lamination direction. The resonators are between the plate electrodes and extend in a first direction. The shield conductors are on respective side surfaces of the laminate body, and connected to the plate electrodes. The resonators are within the laminate body and aligned in a second direction. The resonators each include a first end connected to the shield conductor and a second end spaced apart from the shield conductor. The resonator includes conductors laminated in the lamination direction. When the resonator is viewed in plan from the first direction, the conductors each include a first region including an end portion of the conductor and having a thickness greater than other portions of the conductor.
