    Abstract: A dielectric resonator includes a dielectric block, an external conductor, and wall-surface conductors. The dielectric block has a rectangular parallelepiped shape including a first surface and a second surface opposed to each other. The dielectric block includes a through hole extending from the first surface to the second surface. The external conductor is disposed on an outer surface of the dielectric block. The wall-surface conductors are disposed on a wall surface defining the through hole. The wall-surface conductor includes a first portion of the through hole adjacent to the first surface and a second portion of the through hole adjacent to the second surface. The first and second portions of the wall-surface conductors are separated by a separation distance.

    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.

    Abstract: A filter includes a multilayer body, plate electrodes, resonators, shield conductors, and connecting conductors. The multilayer body includes dielectric layers. The plate electrodes are spaced apart from one another in the multilayer body in a lamination direction thereof. The resonators are between the plate electrodes and extend in a first direction orthogonal or substantially orthogonal to the lamination direction. The shield conductors are on lateral surfaces of the multilayer body and are connected to the plate electrodes. The connecting conductors connect the resonators to the plate electrodes. The resonators are side by side in a second direction in the multilayer body. The resonators each include first and second ends. The first ends are connected to the shield conductor, and the second ends are spaced away from the shield conductor.

    Abstract: A dielectric resonator includes a dielectric substrate, a distributed element, and a shield conductor portion. The distributed element extends in the X-axis direction inside the dielectric substrate. The shield conductor portion is on a surface of the dielectric substrate and winds around the distributed element when the distributed element is viewed from the X-axis direction in plan view. One end of the distributed element is not connected to the shield conductor portion. The distributed element includes a plurality of conductors.
