Abstract: In a vibration device, an operation unit has an operation surface operated by a user. A plurality of piezoelectric elements are disposed so as to overlap the operation surface when viewed from the direction orthogonal to the operation surface. The plurality of piezoelectric elements are disposed at mutually different positions in the direction along the operation surface. A control unit is arranged to control the plurality of piezoelectric elements. The control unit is arranged to vibrate the piezoelectric element corresponding to a first position on the operation surface where an operation is performed at a first frequency and vibrates the piezoelectric element corresponding to a second position on the operation surface different from the first position among the plurality of piezoelectric elements at a second frequency, in response to the operation of the operation surface. The second frequency is a frequency in the audible range.

The fundamental frequency component is lower than the resonance frequency component of the vibration device.
