Piezoelectic element and method for manufacturing the same, and ink jet head and ink jet recording apparatus using the piezoelectric element |
| 摘要 |
A lead content in a piezoelectric thin film ( 3 ) of a piezoelectric element ( 20 ) is made smaller as compared to stoichiometric composition. More specifically, the piezoelectric thin film ( 3 ) is made of lead zirconate titanate expressed as Pb<SUB>(1-x)</SUB>(Zr<SUB>(1-s)</SUB>Ti<SUB>s</SUB>)O<SUB>3</SUB>(0<s<1) or lead-zirconate-titanate-based oxide expressed as (Pb<SUB>(1-x-y)</SUB>A<SUB>y</SUB>)(Zr<SUB>(1-t)</SUB>Ti<SUB>s</SUB>B<SUB>t</SUB>)O<SUB>3</SUB>(0<s<1, 0<t<1-s) where A is a substitutive metal ion in an A-site in the perovskite crystalline structure and B is a substitutive metal ion in a B-site in the perovskite crystalline structure. The value of x, which indicates a deficiency in Pb content in each composition, is more than 0 but not more than 0.15.
