Document Type and Number:
Japanese Patent JP6844980
Kind Code:
B2
Abstract:
The invention relates to a dielectric composition which is a dielectric composition containing calcium titanium silicate, calcium titanate and a manganese-containing compound or a vanadium-containing compound. Under the condition of containing the manganese-containing compound, the content of the calcium titanium silicate is set to be converted into amol% through CaSiTiO5, the content of the calcium titanate is set to be converted into bmol% through CaTiO3, when the content of the manganese-containing compound is set to be converted into the cmol% through MnO2, a is smaller than or equal to 75.0 and greater than or equal to 23.4, b is smaller than or equal to 76.4 and greater than or equal to 21.4, c is greater than or equal to 0.21 and a+b+c is equal to 100. Under the condition of containing the vanadium-containing compound, the content of the calcium titanium silicate is set to be converted into dmol% through CaSiTiO5, the content of the calcium titanate is set to be converted into emol% through CaTiO3, and when the content of the vanadium-containing compound is set to be converted into fmol% through V2O5, d is smaller than or equal to 61.7% and greater than or equal to 23.0, e is smaller than or equal to 76.8 and greater than or equal to 37.9, f is greater than or equal to 0.16 and d+e+f is equal to 100.
