Abstract
A dielectric composition, a dielectric element, an electronic component and a multi-layer electronic component are disclosed. In an embodiment the dielectric composition includes a perovskite crystal structure containing at least Bi, Na, Sr and Ti, wherein the dielectric composition includes at least one selected from among La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Yb, Ba, Ca, Mg and Zn, wherein the dielectric composition includes specific particles having a core-shell structure that has at least one core portion including SrTiOand wherein α is set to 0.20≤α≤0.70, where α is the ratio of the number of specific particles with respect to the total number of particles contained in the dielectric composition.
