Abstract:
A piezoelectric thin film which is of a perovskite type having a tetragonal crystal structure, the tetragonal crystal having a degree of (100) orientation of 80% or higher. The piezoelectric thin film is constituted of a lead lanthanum zirconate titanate (PLZT) which is a lead zirconate titanate (PZT) in which some of the lead has been replaced with lanthanum.
