LAMINATED PIEZOELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a laminated piezoelectric element capable of suppressing insulation degradation even in the case of transmitting displacement to liquid.

SOLUTION: The laminated piezoelectric element PE is provided with a laminated body 1 in which piezoelectric body layers 3 and 5 are interposed and an individual electrode 2 and common electrodes 4 and 19 are alternately laminated. The laminated body 1 is provided with a piezoelectric body layer 9 adjacent to the common electrode 19 positioned at the very end in a laminating direction in the laminated body 1 among the individual electrode 2 and the common electrodes 4 and 19, and constituting one end face in the laminating direction in the laminated body 1. The whole individual electrode 2 adjacent to the common electrode 19 adjacent to the piezoelectric body layer 9 in the laminating direction in the laminated body 1 is hidden by the common electrode 19 adjacent to the piezoelectric body layer 9 in the view from the side of the piezoelectric body layer 9 in the laminating direction in the laminated body 1.
