A dielectric resonator, a dielectric filter, a manufacturing method for the dielectric resonator, and a manufacturing method for the dielectric filter. The dielectric resonator comprises: a solid dielectric resonator body, a blind hole located at one side of the solid dielectric resonator body, a metallized layer covering the solid dielectric resonator body and a surface of the blind hole, and a de-metallized notch located on the metallized layer of the surface of the blind hole. Adopting the dielectric resonator provided in the present invention not only can realize the debugging of the dielectric resonator, but also can reduce the influence to the resonance frequency of the dielectric, generated due to the fact that the de-metallized notch is covered by a metal material in the process of assembling the dielectric resonator after the dielectric resonator is debugged, and can also reduce the signal energy leaking from the notch. |
