A dielectric resonator and a dielectric filter are provided. The inner wall or the outer wall of the dielectric resonator is plated with silver. With the technical solution, it can be guaranteed that the volume of a dielectric resonant column of which the inner wall or the outer wall is plated with silver is reduced by about 35% as compared with the volume of an ordinary dielectric filter, or the volume of the dielectric resonator is reduced under the condition of the same cavity body. In addition, the dielectric resonator is stable and reliable in filtering performance, simple in production process, and overcomes the defect of large size of the universal dielectric resonator in the related art in the low communication frequency band.
