Abstract
The present invention relates to a dielectric composition having a main component and an auxiliary component. The main component is represented by (BiaNabSrcLnd)TiO3, where Ln comprises a rare earth element 0.100≤a≤0.400, 0.100≤b≤0.400, 0.100≤c≤0.700, 0≤d≤0.100, and 0.900≤a+b+c+d≤1.50. The auxiliary component contains a first auxiliary component or a second auxiliary component. The first auxiliary component includes an element selected from the group consisting of Li and K and combinations thereof and the second auxiliary component includes an element selected from the group consisting of Cu, Zn, Mn, Mg and Co and combinations thereof.
