The present invention provides a dielectric composition which is advantageously used for medium- and high-voltage applications with a relatively high rated voltage, which has a high dielectric constant when a high DC bias is applied, both in the region of room temperature and at high temperatures, and which also has superior withstand field characteristics, and also provides a dielectric element employing said dielectric composition, an electronic component, and a laminated electronic component. A dielectric composition containing a main component and an auxiliary component, wherein: the main component is represented by (BiaNabSrcLnd) TiO3; Ln is at least one selected from among rare earth elements; and a, b, c and d satisfy the following: 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≤1.050. The auxiliary component contains a first auxiliary component and/or a second auxiliary component. The first auxiliary component comprises at least one selected from the group consisting of Li and K. The second auxiliary component comprises at least one selected from the group consisting of Cu, Zn, Mn, Mg and Co. |
