摘要: A dielectric ceramic composition which can be formed into a built-in or multilayer structure through simultaneously firing with a low resistance conductor such as Ag or Cu and can be fired at 800 to 1000°C into a dielectric ceramic exhibiting a dielectric constant (ϵr) of 10 or below, a large Qxf0 value and an absolute value of temperature coefficient (tauf) of resonance frequency (f0) of 20 ppm/°C or less whose regulation is easy. The dielectric ceramic composition comprises 5 to 150 pts.wt. of glass component per 100 pts.wt. of main components of the general formula: aZnAl2O4-bZn2SiO4-cTiO2-dZn2TiO4 wherein the molar fractions a, b, c and d of individual components satisfy the relationships: 5.0
