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.
