Patent ID: 6844797

Claim:
A high-frequency dielectric ceramic member comprising an oxide ceramic containing Mg, Ba, Re, Ti, and O, wherein Re is at least one element selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Dy, and Er, wherein the oxide ceramic is represented by the formula aMgO-bBaO-cRe 2 O n -(100-a-b-c)TiO 2 , wherein n=3 when Re is one of La, Nd, Sm, Eu, Dy, and Er, n=11/3 when Re is Pr, and n=4 when Re is Ce, wherein a, b, and c, in mole percent, satisfy the relationships 10.0≦a≦62.0, 0<b≦14.0, and 0<c≦16.5.
