A dielectric resonator which has a simple structure and is easy to manufacture, and a dielectric filter and a communication apparatus using the same are provided. In a dielectric resonator, a dielectric body includes a first portion having surfaces and a second portion having surfaces. A conductor surrounding the dielectric body includes inner surfaces facing the surfaces. A conductor is disposed between the surface and the inner surface. A conductor is disposed between the surface and the inner surface. The dielectric body includes a third portion which is not interposed between the conductors and a fourth portion which is not interposed between conductors. |
