Abstract
The aim of the present invention lies in providing a dielectric composition which has a relatively high dielectric constant of 800 or greater, and which has relatively low dielectric loss of 4% or less 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. A dielectric composition having a main component represented by (BiaNabSrcBad) (αxTi1−x)O3, characterized in that a is at least one selected from Zr and Sn; and a, b, c, d and x satisfy the following: 0.140≦a<0.390, 0.140≦b<0.390, 0.200≦c<0.700, 0.020≦d<0.240, 0.020≦x<0.240 and 0.950<a+b+c+d≦1.050.
