Since the adhesive member 30 having such a buffer layer 32 is disposed between the touch panel 10 and the housing 20, the touch panel 10 can be used when vibrations are generated by the first vibration generator 51 </ b> A and the second vibration generator 52. It becomes easy to move in any of the X direction, the Y direction, and the Z direction, and vibration can be provided to the user appropriately and efficiently.

In the portable information processing apparatus 1A, for example, when a continuous input operation (first input operation) is performed by the user on the touch panel 10, the detection signal S _in is sent from the touch sensor 12 of the touch panel 10 to the touch panel controller 62. Is entered. In response to this, the vibration controller 63 outputs a drive signal S _d1 to the first vibration generator 51A in accordance with an instruction from the main controller 61, and generates continuous vibration (vibration) in the first vibration generator 51A. Let Thereby, the user can recognize that the first input operation has been performed on the touch panel 10.
