<P>PROBLEM TO BE SOLVED: To provide a piezoelectric element and a liquid jet head superior in durability. <P>SOLUTION: The piezoelectric element 100 includes a first conductive layer 10, a second conductive layer 20 disposed facing the first conductive layer 10, and a piezoelectric layer 30 disposed between the first conductive layer 10 and the second conductive layer 20. The piezoelectric layer 30 is composed of a compound oxide containing at least lead, zirconium, titanium, and oxygen, and the compound oxide has a perovskite crystal structure. The piezoelectric layer 30 has a thermally stimulated current having two peaks including a low temperature-side peak and a high temperature-side peak, and the magnitude of the low temperature-side peak is ≤1/30 of that of the high temperature-side peak. <P>COPYRIGHT: (C)2011,JPO&INPIT |
