ABSTRACT:
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(1-x)(Zr(1-s)Tis)O3(0<s<1) or lead-zirconate-titanate-based oxide expressed as (Pb(1-x-y)Ay)(Zr(1-s-t)TisBt)O3(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.
