Patent ID: 7312172

Claim:
A dielectric ceramic composition including at least a main component containing a dielectric oxide having a composition expressed by [(Ca x Sr 1-x )O] m [(Ti y Zr 1-y-z Hf z )O 2 ], a first subcomponent containing a Mn oxide and/or an Al oxide, and a glass component containing at least SiO 2 as a primary component: wherein “m”, “x”, “y” and “z” indicating composition mole ratios in the formula included in said main component are in relationships of 0.90≦m≦1.04 0.5≦x<1 0.01≦y≦0.10 0.5≦z≦0.20, and said dielectric ceramic composition is produced by obtaining a calcinated substance by collectively calcinating at least a main component material, which becomes said main component, a first subcomponent material, which becomes said first subcomponent, and a glass component material, which becomes said glass component, to bring solid phase reaction, and then main firing said calcinated substance.
