Abstract

A tactile-stimulus generation apparatus is enabled to apply an electric stimulus to a fingertip of a user, and a tactile-stimulus generation sheet configured by arranging a tactile-sensation generation electrode group on an insulating layer is installed on a front surface of a capacitive type coordinate input device. The tactile-sensation generation electrode group is distributed at positions where tactile-sensation generation electrodes overlap first or second electrodes of the coordinate input device as seen in plan view. If the fingertip is in proximity with the insulating layer, the fingertip is capacitively coupled to positive and negative electrodes of the tactile sensation generation electrode group to which a differential voltage is applied, and thus, a portion of a current directing from the positive electrode to the negative electrode passes through the fingertip, so that an electric stimulus is applied to the user due to the current.
