PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition to be used for a laminated ceramic capacitor for temperature compensation, by which stable electric properties can be obtained even when it is fired under a non-oxidative atmosphere. SOLUTION: In a three-component composition expressed by formula, x(MgmCa1-m)O-y(TinZr1-n)O2-zLa2O3 (x+y+z=1), wherein x, y, m, n represent molar ratio, the composition but, m is in the range of 0.3-0.70 and n is in the range of 0.70-0.90} within the region surrounded by the points of a(x=0.49, y=0.50, z=0.01), b(x=0.25, y=0.50, z=0.25) and c(x=0.97, y=0.02, z=0.01) is added with at least one selected from the group of BaSiO3, MgSiO3 and CaSiO3 as an additive in amount of 0.05-3.00 wt.% and further, V2O5 in amount of 0.05-0.03 wt.%, based on 100 wt.% of the composition. |
