Dielectric ceramic composition and multilayer ceramic electronic component

Abstract

A dielectric ceramic composition includes a main phase that contains barium titanate with a perovskite structure, a first crystal grain that contains barium, titanium and magnesium, and satisfies 5.00≤a≤7.00 and 0.50≤b≤1.50, where a is an elemental ratio of titanium to barium content, and b is an elemental ratio of magnesium to barium content, and a second crystal grain that contains barium, titanium, magnesium, manganese and nickel, and satisfies 1.50≤c≤3.50, 0.03≤d≤0.30, 0.03≤e≤0.30, and 0.03≤f≤0.40, where an elemental ratio of titanium to barium content is c, an elemental ratio of magnesium to barium content is d, an elemental ratio of manganese to barium content is e, and an elemental ratio of nickel to barium content is f.
