Abstract
Official abstract text for this publication.
[Problem] The problem addressed lies in providing a dielectric composition having a relatively high dielectric constant of 900 or greater when a DC bias of at least 8 V/ym is applied, and also in providing a dielectric element employing said dielectric composition, an electronic component, and a laminated electronic component. [Solution] A dielectric composition in which the composition of the main component is in accordance with the following formula (1): (Bi a Na b Sr c )(Zn d Ti 1 _ d )03 (1) [where a, b, c and d satisfy the following: 0.09≦a≦0.58, 0.09≦b≦0.42, 0.05≦c≦0.84, 0≦d≦0.08, and 0.95≦a+b+c≦1.05].

The invention claimed is: 1. A dielectric composition in which the composition of the main component is in accordance with the following formula (1): (Bi a Na b Sr c )(Zn d Ti 1-d )O 3 (1) characterized in that a, b, c and d satisfy the following: 0.09≦a≦0.58, 0.09≦b≦0.42, 0.05≦c≦0.84, 0≦d≦0.08, and 0.95≦a+b+c≦1.05. 2. The dielectric composition as claimed in claim 1 , wherein a, b, c and d satisfy the following: 0.27≦a≦0.48, 0.18≦b≦0.38, 0.20≦c≦0.60, 0.02≦d≦0.05, and 0.95≦a+b+c≦1.05. 3. A dielectric element comprising the dielectric composition as claimed in claim 1 . 4. An electronic component provided with a dielectric layer comprising the dielectric composition as claimed in claim 1 . 5. A laminated electronic component having a laminated portion formed by alternately laminating an internal electrode layer and a dielectric layer comprising the dielectric composition as claimed in claim 1 .
