Patent ID: 7626803

Claim:
A dielectric ceramic having a composition represented by the general formula: 100(Ba 1−w−x−m Ca w Sr x Gd m ) k (Ti 1−y−z−n Zr y Hf z Mg n )O 3+a +pMnO 2 +qSiO 2 +rCuO, wherein (Ba 1−w−x−m Ca w Sr x Gd m ) k (Ti 1−y−z−n Zr y Hf z Mg n )O 3+a is a primary component, k, w, x, y, z, m, n, p, q and r are each mole values, 0.995≦k≦1.010, 0≦w<0.04, 0≦x≦0.04, 0≦y≦0.10, 0≦z≦0.05, 0.015≦m≦0.035, 0.015≦n≦0.035, 0.01≦p≦1.0, 0.5≦q≦2.5, 0.01≦r≦5.0, and a is a value selected with respect to the deviation from 3 so that the primary component is electrically neutral.
