<p><P>PROBLEM TO BE SOLVED: To provide a liquid jetting head capable of suppressing destruction of a piezoelectric element and excellent in displacement characteristic, and to provide a liquid jetting apparatus. <P>SOLUTION: The piezoelectric element 300 has a first common electrode 60, a first piezoelectric layer 65, an individual electrode 70, a second piezoelectric layer 75, and a second common electrode 80 sequentially layered therein. The individual electrode 70 is prepared to correspond to a pressure generation chamber 12 and covered with the second piezoelectric layer 75. The second common electrode 80 covers the second piezoelectric layer 75 and is continuously formed all over in a side-by-side arrangement direction of the pressure generation chamber 12. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
