液滴吐出装置
Document Type and Number:
Japanese Patent JP4774666
Kind Code:
B2
Abstract:
A piezoelectric device includes a piezoelectric body layer, a first electrode layer at one face side of the piezoelectric body layer, and a second electrode layer at a side of a face of the same that is opposite to the side at which the first electrode layer is disposed. Higher potentials are applied to the first electrode layer and lower potentials are applied to the second electrode layer. The piezoelectric device features a metallic layer disposed in contact with a piezoelectric body layer surface at the side at which the first electrode layer is provided, and a metal oxide layer disposed in contact with a piezoelectric body layer surface at the side at which the second electrode layer is provided. The metallic layer is formed of a metallic material with a standard electrode potential greater than 0 V, and the metal oxide layer is formed of a metal oxide.
