    Abstract: A multilayer ceramic capacitor includes a base body including first and second main surfaces, first and second side surfaces, first and second end surfaces, and dielectric layers and internal electrode layers, and external electrodes at the first and second end surfaces, and electrically connected to the internal electrode layers. The base body includes an inner layer, first and second outer layers, first and second side margin portions. The dielectric layers in the inner layer and the first and second outer layers include main crystal grains including barium and titanium, and with respect to 100 parts by mol of titanium, nickel in an amount of about 0.2 to about 3.0 parts by mol, and at least one rare earth element selected from yttrium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium in an amount of about 0.6 parts to about 2.0 parts by mol.
