Abstract:
1. A multilayer ceramic electronic component comprising an element body in which a dielectric layer and an internal electrode layer are stacked, wherein said dielectric layer is constituted from a dielectric ceramic composition including; a compound having a perovskite type crystal structure expressed by a general formula of ABO an oxide of Mg; an oxide of R element, where R element is one selected from a group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; and an oxide including Si, said dielectric ceramic composition comprises a plurality of dielectric particles and a grain boundary present in between said dielectric particles adjacent to each other, in said grain boundary, wherein a content ratio of said Mg is set to D(Mg) and a content ratio of said Si is set to D(Si), said D(Mg) is 0.2 to 1.8 wt % in terms of MgO, and said D(Si) is 0.4 to 8.0 wt % in terms of SiO
