Abstract
A multilayer capacitor having a hexagonally-shaped capacitor body, a first internal electrode arranged therein, and a second internal electrode arranged below the first internal electrode separated by a ceramic layer. The capacitor body is provided with a first through-hole electrode passing through the second non-contact hole, of the second internal electrode and electrically connected to the first internal electrode and a second through-hole electrode passing through the first non-contact hole of the first internal electrode and electrically connected to the second internal electrode in columnar shapes extending to intersect the internal electrodes. The first through-hole electrode is electrically connected to the first external electrodes arranged in island shapes at the upper and lower flat portions. The second through-hole electrode is electrically connected to the second external electrodes arranged in island shapes at the surfaces of the capacitor body.
