Abstract:
1. A dielectric ceramic composition including at least a main component containing a dielectric oxide having a composition expressed by [(Ca a first subcomponent containing a Mn oxide and/or an Al oxide, and a glass component containing at least SiO wherein “m”, “x”, “y” and “z” indicating composition mole ratios in the formula included in said main component are in relationships of 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.
