Patent ID: 10759705

Abstract:
A dielectric composition has barium, strontium, and bismuth calcium titanates constituting a main component and subcomponent. “a” mol % represents a content of barium titanate in terms of BaTiO3, “b” mol % strontium titanate in terms of SrTiO3, and “c” mol % bismuth calcium titanate in terms of CaBi4Ti4O15 in the main component composition. a+b+c=100 is satisfied, 50≤a≤83, 12≤b≤49.5, 0.5≤c≤5. The dielectric composition includes a first subcomponent constituted by at least one compound including one of manganese, iron, and chromium. The first subcomponent is included in a ratio of 0.2 wt % or more and 3 wt % or less in terms of total of MnCO3, Fe2O3, and Cr2O3 with respect to 100 wt % of the main component. The dielectric composition includes a second subcomponent compound including niobium, included in a ratio of 0.1 wt % or more and 3 wt % or less in terms of Nb2O5 with respect to 100 wt % of the main component.
