摘要： The dielectric resonator of the invention comprises a cavity having a first threaded hole, a dielectric block provided in the cavity, a coupling device coupled with an electromagnetic field produced in the cavity, a frequency tuning member having a screw portion which is spirally engaged with the first threaded hole of the cavity, a distance between the dielectric block and the frequency tuning member being changed by rotating the frequency tuning member, for tuning a resonance frequency of the cavity depending on the distance, fixing means for fixing a relative positional relationship between the frequency tuning member and the cavity. The fixing means fixes the cavity and prevents the frequency tuning member from rotating due to a frictional force caused between the first threaded hole of the cavity and the screw portion of the frequency tuning member.
