Abstract
A dielectric composition includes main-phase particles each including a main component having a perovskite crystal structure represented by a general formula of ABO. At least a part of the main-phase particles has a core-shell structure. The dielectric composition includes RA, RB, M, and Si. Each of A, B, RA, RB, and M is one or more elements selected from a specific element group. S/S>C/Cis satisfied, where Cis an RA content (mol %) to the main component in terms of RAO, and Cis an RB content (mol %) to the main component in terms of RBO, in the dielectric composition, and Sis an average RA content (mol %), and Sis an average RB content (mol %), in a shell part of the core-shell structure.
