摘要：
A dielectric resonator is disclosed which includes a case having a resonator main body portion, an upper lid and a lower lid. Inside the case is a cylindrical dielectric material. The case is formed of a dielectric material having the same coefficient of linear expansion as the cylindrical dielectric material. In one embodiment, main body portion comprises a dielectric case side portion with the cylindrical dielectric material disposed concentrically in a concavity defined by the case side portion, with the cylindrical dielectric material being integrally coupled to the dielectric case side portion by four connecting portions. More specifically, in this embodiment, the case side portion of the main body portion and the cylindrical portion are simultaneously and integrally formed of the same dielectric material. A conductive film is formed to enclose a region surrounding the cylindrical dielectric material. In one embodiment, the conductive film is formed on the whole outer surface of the dielectric case side portion and conductive films and are also formed on the lower surface of the upper lid and the upper surface of the lower lid.
