    摘要: A dielectric ceramic composition including dielectric particles comprising a main ingredient phase having barium titanate as its main ingredient and a diffusion phase present at the periphery of said main ingredient phase, wherein when an average value of the depth where sub ingredient elements present at said diffusion phase diffuses from a surface of said diffusion phase toward a center of said dielectric particle is designated as an average diffusion depth, a dispersion of the average diffusion depth among the dielectric particles is, in terms of CV value, 5 to 30%. According to the present invention, an electronic device excellent in all of the dielectric constant, high temperature accelerated life, TC bias, and IR temperature dependency can be provided.
