摘要：A dielectric ceramic composition comprised of at least dielectric particles having
barium titanate as its main ingredient, wherein the ratio of dielectric particles having asurface diffusion structure comprised of a main ingredient phase comprised of the mainingredient and a diffusion phase present around the ingredient phase with respect to saiddielectric particles is 60% or more the ratio of dielectric particles having a domain in themain ingredient phase with respect to the dielectric particles having the surface diffusionstructure is 20% or less. According to the present invention, a dielectric ceramic
composition and electric device realizing good high temperature accelerated life can beprovided.
