Abstract:
1. A dielectric ceramic composition comprising: a main component having a perovskite-type crystal structure represented by a general formula ABO at least one or more subcomponent elements, wherein: said dielectric ceramic composition has a dielectric particle and a grain boundary, said dielectric particle has a main component phase substantially composed of said main component, and a diffusive phase around said main component phase in which at least one selected from said subcomponent elements is diffused, when said dielectric particle is cut on an arbitrary cutting plane including said main component phase: Cs is defined as a concentration of one or more elements selected from said subcomponent elements in an arbitrary position in said dielectric particle, and “D” is defined as a length of a cross-sectional line from an arbitrary outside edge of the dielectric particle in said cutting plane passing through a centroid of the main component phase in said cutting plane to a facing arbitrary outside edge.
