| 内容： | To provide an electronic device such as a multilayer capacitor wherein the temperature characteristic of the electrostatic capacity is capable of satisfying both the X7R characteristics (EIA standard) and the B characteristics (EIAJ standard), the electrostatic capacity and the insulation resistance show little voltage dependency, the insulation breakdown resistance is excellent and Ni or a Ni alloy can be used as an internal electrode layer, a dielectric ceramic composition suitably used as a dielectric layer of the electronic device, and a method for producing the same. ! The dielectric ceramic composition comprises barium titanate and component M (wherein M is at least one chosen from the group consisting of manganese oxide, iron oxide, cobalt oxide and nickel oxide) as main components and has a ferroelectric phase region, wherein the concentration of the component M in the ferroelectric phase region changes from the outside toward the center. !
