A dielectric resonator to be advantageously used in 0.5-6 GHz band and having a large unloaded Q value, and adequate relative dielectric constant, a good stability of tau f and a superior linearity of temperature characteristic of the resonance frequency, may be constituted by the dielectric porcelain composition expressed by the formula: BaxSryCaz(Zn1/3Nb2/3)1-t TitO3 in which x+y+z=1, x is within the range of 0 to 0.5, y is within the range of 0.5 to 0.999, z is within the range of 0.001 to 0.20 and t is within the range of 0.001 to 0.25. |
