Abstract
A dielectric composition, a dielectric element, an electronic component and a laminated electronic component are disclosed. In an embodiment the dielectric composition includes particles having a perovskite crystal structure including at least Bi, Na, Sr and Ti, wherein the content of the at least one element selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Yb, Ba, Ca, Mg or Zn is between 0.5 molar parts and 11.1 molar parts, taking the Ti content of the dielectric composition as 100 molar parts, wherein 0.17≤α≤2.83, where α is the molar ratio of Bi with respect to Sr in the dielectric composition, and wherein at least some of the particles include a high-Bi phase having a Bi concentration of at least 1.2 times the mean Bi concentration of the dielectric composition as a whole.
