    摘要： A multilayer ceramic electronic component comprising an element body in which a dielectric layer and an internal electrode layer are stacked. The dielectric layer is constituted from a dielectric ceramic composition including; a compound having a perovskite structure expressed by a formula of ABO3 (A is at least one selected from Ba, Ca, and Sr; B is at least one selected from Ti, Zr, and Hf); an oxide of Mg; an oxide of rare earth elements including Sc and Y; and an oxide including Si. The dielectric ceramic composition comprises a plurality of dielectric particles and a grain boundary present in between the dielectric particles. In the grain boundary, when content ratios of Mg and Si are set to D(Mg) and D(Si) respectively, D(Mg) is 0.2 to 1.8 wt % in terms of MgO, and D(Si) is 0.4 to 8.0 wt % in terms of SiO2.
