Claim 0:
1. A tactile presentation device, comprising:
a panel;
a first supporting member that secures and supports a first end of the panel;
a vibration generator disposed at a position facing the first supporting member across a target area to be touched by a user on the panel; and
a driving control device that provides the vibration generator with a driving signal,
wherein the driving control device makes only the vibration generator vibrate to form a standing wave in an area including the target area between the vibration generator and the first end,
wherein a first vibration reflection rate at the first end for a carrier wave from the vibration generator is negative, and
wherein a second vibration reflection rate for the carrier wave from the vibration generator at a second end of the panel that is a free or an absorption end opposing to the first end across the vibration generator is greater than the first vibration reflection rate.
