PROBLEM TO BE SOLVED: To provide a dielectric resonator that can suppress influence to a Q value and a temperature coefficient by means of a supporting stand. SOLUTION: A dielectric resonator 1 is formed by an almost columnar or cylindrical dielectric resonance element 2 formed of a dielectric porcelain material, an almost-cylindrical supporting stand formed of a dielectric porcelain material and a metal case 5. The dielectric resonance element 2 is molded of the BCN-BZN system porcelain material of a high dielectric constant and the supporting stand 3 is molded of a forsterite (2MgO SiO2) porcelain material. High temperature curing epoxy resin 4 is applied to the center area of the base of the dielectric resonance element 2 by a screen printing method and the like. The supporting stand 3 is fixed to the base of the dielectric resonance element 2 and it is heated so that high temperature curing epoxy resin 4 is sandwiched. Thus, the dielectric resonance element 2 is integrated on the supporting stand 3.
