Patent abstract
A dielectric ceramic composition containing a dielectric material and a glass, characterized in that the dielectric material is represented by the compositional formula a·Li2O-b·(CaO1-x—SrOx)-c·R2O3-d·TiO2 (wherein x satisfies 0≦x<1; R is at least one selected from La, Y and other rare-earth metals; and a, b, c and d satisfy 0≦a≦20 mol %, 0≦b≦45 mol %, 0<c≦20 mol %, 40≦d≦80 mol % and a+b+c+d=100 mol %.) and the glass contains at least 30 % by weight of Bi2O3.
