Abstract
The present invention relates to a stacked piezoelectric ceramic element and can provide a stacked piezoelectric ceramic element produced by stacking two or more ceramic green sheets, the stacked piezoelectric ceramic element having a structure in which a ceramic porous or defective part constituting the stacked piezoelectric ceramic element is impregnated with an organic resin, thereby improving waterproof performance capable of preventing the deterioration of insulation resistance in a highly humid environment.
