ABSTRACT:
Disclosed is a multilayer capacitor using a sintered body obtained by alternately laminating a plurality of ceramic green sheets each having first inner electrodes formed on its one major surface and a plurality of ceramic green sheets each having second inner electrodes extending in such a direction as to intersect the first inner electrodes formed on its one major surface and cofiring the same. The first inner electrodes are spaced apart from each other through a space region having a predetermined width in the same plane, and led out to first and second side surfaces of the sintered body. In addition, each of the second inner electrodes is let out to third and fourth side surfaces of the sintered body, and has a plurality of electrode portions for taking up capacitance overlapped with the first inner electrodes through a ceramic layer. A first outer electrode is formed on at least one of the first and second side surfaces of the sintered body, and at least one pair of second outer electrodes is formed on the third and fourth side surfaces of such body. Portions other than the electrode portions for taking up capacitance of each of the second inner electrodes are formed to have a width smaller than that of each of the electrode portions for taking up capacitance.
