Abstract:
A vibration structure that includes a piezoelectric film constructed to deform in a plane direction as a voltage is applied thereto, a frame-shaped member, a vibration portion surrounded by the frame-shaped member in a plan view of the vibration structure, a support portion connecting the vibration portion and the frame-shaped member, and supporting the vibration portion within the frame-shaped member such that the vibration portion vibrates in the plane direction when the piezoelectric film is deformed in the plane direction, a first connection member that connects the piezoelectric film to the vibration portion, and a second connection member that connects the piezoelectric film to the frame-shaped member. Of the connection members, the first connection member is disposed between the center of gravity of the vibration portion and the second connection member.
