Abstract: A perovskite ceramic composition that contains Sn, Ba, and Ti, and where the Sn content is within a range of about 0.001 parts by mol≤Sn≤about 0.999 parts by mole with respect to 100 parts by mole of the Ti. The perovskite ceramic composition can be used in a composition that further includes a rare earth element R, Mn, and Si, and optionally Mg, where proportions of the R, the Mn, the Si, and the optional Mg, satisfy R: 0

Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric ceramic layers and inner electrode layers containing Ni and electrically connected to outer electrodes. The dielectric ceramic layers contain a Ba- and Ti-containing perovskite compound, Ca, Mg, R (at least one rare earth metal selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y), M (at least one selected from Zr, Mn, Co, Fe, Cr, Cu, Al, V, Mo, and W), and Si. The number of parts by mole of each element relative to Ti as 100 parts is as follows: Ca, approximately 0.10 to 5.00 parts; Mg, approximately 0.0010 to 0.0098 parts; R in total, approximately 0.50 to 4.00 parts; M in total, approximately 0.10 to 2.00 parts; and Si, approximately 0.5 to 2.0 parts.
