PROBLEM TO BE SOLVED : To improve moisture resistance of a multilayer ceramic capacitor. SOLUTION : A multilayer ceramic capacitor 10 includes : a laminate 11 in which a plurality of dielectric ceramic layers 122 and inner electrodes 13a, 13b are alternately laminated; and a pair of outer electrodes provided outside the laminate 11. The dielectric ceramic layer 122 positioned between the inner electrodes, a first region 123a positioned between the inner electrode and a first side surface 17a in a width direction, and a second region 123b positioned between the inner electrode and a second side surface 17b include a perovskite compound containing Ba and Ti, and at least one element selected from a group consisting of Ba, Mg, Mn, and rare earth. In the dielectric ceramic layer 122, the first region 123a, and the second region 123b, when a mole ratio with respect to the at least one element is defined as Sa, S1, ans S2, respectively, relations S1
