Abstract: A tactile presentation device includes 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. 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. A first vibration reflection rate at the first end for a carrier wave from the vibration generator is negative. A second vibration reflection rate for the carrier wave from the vibration generator at a second end of the panel that is opposing to the first end across the vibration generator is greater than the first vibration reflection rate.
