Abstract: A multilayer ceramic capacitor may include: a ceramic body that includes dielectric layers and internal electrodes; an external electrode including a connection portion that covers an end surface of the ceramic body and a band portion that extends from the connection portion to cover a side surface of the ceramic body; a first cover layer disposed between the internal electrode closest to the side surface and the side surface; a second cover layer opposing the first cover layer; an active region in which the internal electrodes overlap and spaced apart from the end surface by a first distance, a first dummy electrode disposed in the first cover layer, and a seed electrode layer disposed between the band portion and the first cover layer, wherein a length of the seed electrode layer is greater than the first distance and greater than a length of the first dummy electrode.
