Patent ID: 8652984

Claim:
A dielectric ceramic composition comprising: a main component having a perovskite-type crystal structure represented by a general formula ABO 3 , and 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: a first local maximum value of Cs exists in an intermediate section that is between a position corresponding to a length of 10% of a length “D” of a cross-sectional line from an outside edge of the particle and a position corresponding to a length of 30% of the length “D” of said cross-sectional line from said outside edge, a local minimal value of Cs is located at a side of the outside edge with respect to a position of said first local maximum value of Cs, and Cs is increased from a position of said local minimal value of Cs toward said outside edge, and a second local maximum value of Cs exists in the outside edge of said dielectric particle, 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.
