Abstract
[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): (BiaNabSrc)(ZndTi1_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].
