Patent ID: 7003858

Claim:
A method of manufacturing a piezoelectric component comprising the steps of: printing an internal electrode and a dummy electrode on a green sheet; printing a floating electrode on a green sheet; stacking a plurality of green sheets, each having the internal electrode and the dummy electrode printed thereon, and the green sheet on which the floating electrode is printed, to obtain a layered product in which at least one floating electrode layer is arranged in at least one of the green sheets between the adjacent internal electrodes in the stacking direction and/or green sheets outside the outermost internal electrodes in the stacking direction, a plurality of the internal electrodes are extended to opposite first and second sides alternately in the thickness direction, and the dummy electrode is arranged between an end of the internal electrode opposite to the side extended to one of the sides and the other side to which the internal electrode is not extended; firing the layered product to obtain a sintered ceramic compact body; respectively forming first and second external electrodes on the first and second sides of the sintered ceramic compact body; and applying a DC electric field between the first and second external electrodes to polarize the sintered ceramic compact body.
