PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition of a large relative dielectric constant (εr ), a large no-load Q value and a small temperature coefficient of resonance frequency and obtain a dielectric porcelain composition which can use Ag, Ag-Pd, Cu or the like as an inner electrode and can laminate them simultaneously by low-temperature sintering. SOLUTION: This dielectric porcelain composition contains, as the main components, Ba, Ti, Vd, Sm and oxygen represented by the formula: xBaO- yTiO2 -zNd2 O3 -tSm2 O3 (where 0.1<=x<=0.2, 0.5<=y<=0.8, 0.01<=z<=0.2, 0<=t<=0.2, and x+y+z+t=1). Additionally, this composition contains, as sub-components, glass powder with a softening point of <=500 deg.C and the content of the sub- component to the main components is >=1 but >=25 in wt.%. |
