Patent number: 9536668
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.
