Vibration-type piezoelectric acceleration sensor element and vibration-type piezoelectric acceleration sensor therewith

Image Number 2 for United States Patent #7168321.

The vibration-type piezoelectric acceleration sensor element includes a frame; and a diaphragm, support, and retentive part, provided in the frame. The diaphragm includes a bottom electrode layer, a piezoelectric thin-film layer formed on the bottom electrode layer, and a top electrode layer formed on the piezoelectric thin-film layer. A first end of the diaphragm is connected to the frame. The support retains a second end of the diaphragm. The retentive part retains the support so that the support is reciprocable only in a direction through the first end and the second end of the diaphragm.
