Abstract
In order to provide a dielectric composition having high relative permittivity at a wide range of temperatures, the main component of a dielectric composition includes strontium and tantalum.
Claims6
A dielectric composition comprising a main component including strontium and tantalum,
- wherein the main component is defined as a component that occupies 80-100 parts by mol with respect to 100 parts by mol of elements other than oxygen contained in the dielectric composition,
- wherein the main component is expressed by {BaxSr(1-x)}mTa4O12 and the value of x is 0.75 or smaller, wherein the value of m is 1.8-2.2, and
- wherein a total of titanium, niobium, alkali metals, and lead occupies 10 parts by mol or less but greater than 0 parts with respect to 100 parts by mol of the elements other than oxygen contained in the dielectric composition.
