Piezoelectric element, ultrasonic sensor, discharging head, ultrasonic device, liquid discharging device, and method of manufacturing piezoelectric element
A supporting film is provided on an opening and a wall of a substrate. A piezoelectric film is provided on a first region of the supporting film corresponding to the opening and a second region of the supporting film corresponding to the wall. The thickness of the piezoelectric film at the second region is smaller than that of the piezoelectric film provided at the first region. Therefore, vibration of the piezoelectric film in the first region is large, and vibration of the piezoelectric film in the second region is small. This alleviates disadvantages such as a loss of the vibration characteristics of a piezoelectric element. |
