ABSTRACT:
A laminated electronic component includes a ceramic body having an inner portion and a pair of outer portions disposed above and below the inner portion and a pair of external electrodes disposed on lateral sides of the ceramic body. A plurality of internal electrodes are embedded in the inner portion and alternately connected to the external electrodes. At least two layers of dummy electrodes are embedded in at least one of the outer portions and each connected to one of the external electrodes. An innermost one of the dummy electrodes has a same polarity as an adjacent outermost one of the internal electrodes. The dummy electrodes include at least one pair of adjacent dummy electrodes of opposite polarities.
