IPC: H01L41/22
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric element obtaining a sufficient bending displacement even by reducing its size and having high durability and reliability. SOLUTION: A lower electrode 22 is formed on a substrate 21 made of zirconia. A piezoelectric 23 made of PZT(lead zirconate titanate) is formed in a larger area than the electrode 22 to cover the electrode 22. A reactive layer 25 is formed on a part where the piezoelectric 23 of the outer periphery is brought into direct contact with the substrate 21.
