Provided is a piezoelectric element vibration apparatus that generates vibration by applying a driving voltage to a piezoelectric vibrator, wherein a piezoelectric element layer is arranged on an electrode substrate made of a conductive material, an insulation member for preventing the applied driving voltage from leaking is formed on the piezoelectric element layer, and the piezoelectric element vibration apparatus has various types of forms in order to attach and install the piezoelectric vibrator. As a result, the piezoelectric element vibration apparatus has the effects wherein: installation is possible simply by attachment, thereby simplifying the assembly process; installation in any position is possible because the thickness of the piezoelectric element vibration device is made to be thin; the vibration volume can increase and the vibration noise can decrease while minimizing the thickness.
