Abstract
A dielectric composition includes main-phase particles each including a main component having a perovskite crystal structure represented by a general formula of ABO3. 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. SRA/SRB>CRA/CRB is satisfied, where CRA is an RA content (mol %) to the main component in terms of RA2O3, and CRB is an RB content (mol %) to the main component in terms of RB2O3, in the dielectric composition, and SRA is an average RA content (mol %), and SRB is an average RB content (mol %), in a shell part of the core-shell structure.
