Beschreibung
Zusammenfassung:	PURPOSE: Provided is a low temperature co-firing dielectric ceramic composition, which has a high dielectric constant, low dielectric loss and excellent stability of dielectric constant against temperature so as to reduce the volume of multilayer ceramic module-type electronic components and to improve the characteristic property of the component. CONSTITUTION: The ceramic composition comprises: (a) x(Ba,Sr)O·y(Ti,Zr)O2·z(Nb,Ta)2O5 as a main component, (b) a firing aid, and (b) a bonding modifier, wherein the main component is represented by the formula of x(aBaO,(1-a)SrO)·y(bTiO 2,(1-b)ZrO2)·z(cNb2O5,(1-c)Ta2O5), in which 0.15
