WIPO Patent Application WO/2023/074616
Kind Code:
A1
Abstract:
A thermistor-mounted piezoelectric vibration device (1) is provided with a sand device (2), and a thin-plate thermistor (5) which is mounted on an outside surface of a first sealing member (20) in the sand device (2). The thin-plate thermistor (5) is disposed so as to overlap with at least a portion of a vibration section (13) of the sand device (2) in plan view. Furthermore, a piezoelectric vibration plate (10) in the sand device (2) has the vibration section (13), an outer frame section (14) which encloses the outer periphery of the vibration section (13), and a retention section (15) which retains the vibration section (13) by linking the vibration section (13) and the outer frame section (14). The thin-plate thermistor (5) is disposed so as to overlap the outer frame section (14) on two mutually opposing sides of the sand device (2).
