According to the present invention, the moisture resistance of a multilayer ceramic condenser is improved. The multilayer ceramic condenser (10) includes a laminate (11) in which dielectric ceramic layers (122) and internal electrodes (13) are alternately laminated, and a pair of external electrodes (14) provided outside the laminate (11). A dielectric ceramic layer (122) disposed between the internal electrodes, a first region (123a) disposed between the internal electrodes (13) and a first side surface (17a) in the width direction, and a second region (123b) disposed between the internal electrodes (13) and a second side surface (17b) include a perovskite-type compound including Ba and Ti, and at least one element selected from the group consisting of Ba, Mg, Mn, and rare earth elements. In the dielectric ceramic layer (122), the first region (123a), and the second region (123b), when a molar ratio of the at least one element to Ti is Sa, S1, and S2, respectively, a relationship of S1< Sa and S2< Sa is established.COPYRIGHT KIPO 2018
