A multilayer ceramic capacitor includes: a multilayer structure in which dielectric layers and internal electrode layers are alternately stacked; wherein a main component of the dielectric layers is a ceramic material having a main phase having a perovskite structure (ABO3) wherein a B site includes an element solid-solved in the B site and acting as a donor; wherein an A site and the B site of the ceramic material includes a rare earth element, wherein (an amount of the rare earth element substitutionally solid-solved in the A site)/(an amount of the rare earth element substitutionally solid-solved in the B site) is 0.75 or more and 1.25 or less. The amount of the element acting as the donor in the B site is 0.05 to 0.3 atm % relative to a main component element of the B site.
