Abstract
A multilayer ceramic electronic device includes an element body including a dielectric layer and an electrode layer laminated. The dielectric layer contains a main component represented by ABO. The dielectric layer contains above 0 mol and less than 0.050 mol Mn oxide in terms of MnO; 1.00 mol or more and 2.50 mol or less Mg oxide in terms of MgO; 0.50 mol or more and 1.50 mol or less R oxide in terms of RO, where R includes at least one of Y, Dy, Ho, Yb, Lu, Gd, and Tb; and 0.05 mol or more and 0.45 mol or less Zr oxide in terms of ZrO, with respect to 100 mol of the main component and further contains Si. The dielectric layer has a Zr/Mn ratio of 5.0 or more and 12.5 or less and a Zr/Si ratio of 0.40 or more and 0.80 or less in atomic ratio.
