Abstract
A piezoelectric vibrator that includes a piezoelectric film with a pair of electrodes disposed on opposing sides of the piezoelectric film. Moreover, the vibrator includes first and second adjustment films with the first adjustment film covering the first surface of the piezoelectric film in a first region and the second adjustment film covering the first surface of the piezoelectric film in a second region that is different from the first region. Moreover, the second region of the piezoelectric film has a greater displacement than the first region when the piezoelectric vibrator vibrates.
