LIQUID EJECTING HEAD, LIQUID EJECTING APPARATUS, AND PIEZOELECTRIC ELEMENT |
摘要 |
A liquid ejecting head that discharges a liquid through a nozzle aperture includes a piezoelectric element. The piezoelectric element includes a piezoelectric layer and a first and a second electrode provided for the piezoelectric layer. The piezoelectric layer is made of a complex oxide containing bismuth, iron, barium and titanium and having a perovskite structure. The iron content in the piezoelectric layer is higher at the interface with the second electrode than other portions in the thickness direction of the piezoelectric layer.
