1. A multilayer ceramic capacitor comprising:
an element body that includes a laminate, the laminate having a plurality of inner electrode layers stacked via dielectric layers, a height of the laminate in a stacking direction of the inner electrode layers being greater than a width of each of the inner electrode layers; and
a pair of external electrodes formed on the element body such that one of the pair of the external electrodes is connected to every other ones of the plurality of inner electrode layers and the other of the pair of the external electrodes is connected to the remaining every other ones of the plurality of inner electrode layers,
wherein the element body has a plurality of faces including a pair of opposing end faces and four faces that are perpendicular to the end faces, the four faces including a top face, a bottom face, a front face, and a rear face, the plurality of inner electrode layers include first inner electrode layers and second inner electrode layers such that the first inner electrode layers are exposed at one of the end faces and the second inner electrode layers are exposed at the other of the end faces, one of the pair of external electrodes is formed on the one of the end faces and extends therefrom onto neighboring areas of the bottom face, the front face, and the rear face and only the bottom face, the front face, and the rear face among the four faces of the element body, and the other of the pair of external electrodes is formed on the other of the end faces and extends therefrom onto neighboring areas of the bottom face, the front face, and the rear face and only the bottom face, the front face, and the rear face among the four faces of the element body,
wherein each of the external electrodes has front and rear portions that cover the corresponding neighboring areas of the front face and the rear face of the element body, and each of the front and rear portions has an upper edge that is lower than the top face of the element body, and
wherein each of the external electrodes has an end-covering portion that covers the corresponding end face of the element body, and the end-covering portion has an upper edge that has a height that is equal to that of the top face of the element body.
