Abstract: A vibration device includes a first vibration plate having a length direction, the first vibration plate including a first end portion at one end in the length direction and a second end portion at another end in the length direction, a first piezoelectric element provided on the first vibration plate, a first conductive wiring line joined to the first piezoelectric element at a position closer to the first end portion in the length direction than a center of the first vibration plate, a first fixed component connected to the first conductive wiring line, and a case component to which the first fixed component is fixed. The second end portion is a free end, and the first conductive wiring line includes a bent portion.
