PROBLEM TO BE SOLVED: To provide a laminated piezoelectric element removing parasitic capacitance, and to provide a piezoelectric vibration module.SOLUTION: A piezoelectric element 1000 includes a laminate 100 including a plurality of piezoelectric layers 110, and an internal electrode layer 120 formed between adjacent piezoelectric layers, an electrode 200 formed in the laminate 100 so as to apply charges, having polarities different from each other, to the adjoining internal electrode layers 120, and a ground part 300 formed in the laminate 100 in order to remove a parasitic capacitance generated therein, and is connected with at least any one of the internal electrode layers 120.SELECTED DRAWING: Figure 1 |
