PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition and a dielectric resonator, having a low dielectric constant and a high Q value when measured at a frequency of 10GHz (room temperature) and capable of improving burning conditions. SOLUTION: A dielectric porcelain composition is complex oxides of Mg, Al, and Si as metal elements and comprises 60 to 99.9% main components such that when its composition formula given in the mole ration of the metal element oxides is xMgO.yAl2 O3 .zSiO2 , (x), (y), and (z) meet 10<=x<=40, 10<=y<=40, 20<=z<=80, and x+y+z=100, and 0.1 to 40wt.% Ce or Ti in terms of CeO2 or TiO2 . The dielectric porcelain composition has characteristics such that its specific dielectric constant is 7 or less and a Q value at a frequency of 10GHz (room temperature) is 3000 or more. |
