Abstract

A dielectric resonator comprises a disk-shaped dielectric resonator body having a through hole at the center, a supporting member for supporting the resonator body, and a screw fixing member for fixing the resonator body on the supporting member, in which the supporting member is made of resin material and is intended to be mounted on a mounting surface, and the resonator body is held between the supporting member and the holding portion of the screw fixing member.
