Abstract:
A vibrating body is accommodated in a vibrating body case in a state where both sides of the vibrating body containing a piezoelectric material are sandwiched between buffer portions from a direction intersecting a bending direction of the vibrating body, and the buffer portions are pressed against the vibrating body using a pressing lid through elastic portions. Pressing plates are provided between the buffer portions and the elastic portions to restrict the movement of the pressing plates in a vibration direction of the vibrating body.
