The problem addressed lies in providing a dielectric composition having a relatively high dielectric constant of 800 or greater when a DC bias of at least 8 V/μm 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)(MgdTi1-d)O3 (1) [where a, b, c and d satisfy the following: 0.10≦a≦0.65, 0
