Patent ID: 7153800

Claim:
A dielectric ceramic composition containing a dielectric material and a glass, characterized in that said dielectric material is represented by the compositional formula a·Li 2 O-b·(CaO 1-x -SrO x )-c·R 2 O 3 -d·TiO 2 (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 said glass contains at least 30% by weight of Bi 2 O 3 .
