Abstract
A thin film piezoelectric element has a laminate including a piezoelectric film and a pair of electrode films placed so as to sandwich the piezoelectric film in between, a resin film formed so as to cover the laminate, and an electrode formed on the resin film and electrically connected to the electrode film. The resin film is formed so that a thickness of a region where the electrode is formed is larger than a thickness of a region corresponding to a displaced portion of the laminate.
