PIEZOELECTRIC ELEMENT, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid-jet head which has a piezoelectric element free from lead, having a high insulation property, and capable of suppressing generation of leak current.SOLUTION: A liquid-jet head comprises a pressure generation chamber 12 in communication with a nozzle opening 21 and a piezoelectric element 300 comprising: a first electrode 60; a piezoelectric layer 70 formed on the first electrode 60 and containing iron manganese acid bismuth lanthanum; and a second electrode 80 formed on the piezoelectric layer 70. The piezoelectric layer 70 further contains titanium.
