Abstract
A dielectric ceramic composition having a high dielectric constant. The dielectric ceramic composition is sinterable at a low sintering temperature and has superior electrical and temperature characteristics. The dielectric ceramic composition comprises 100 parts by weight of a dielectric ceramic component represented by the general formula Ba{(Co Zn ) Nb } O , in which, on a molar basis, 0<x<1, 0.313≦y<0.333, 0.993≦z<1, and w is an optional number, and 1 to 25 parts by weight of a SiO —B O -based glass component is mixed therewith.
