In an electric stimulus using array-form electrodes, a deep nerve axon is favorably stimulated without compromise in spatial resolution of tactile stimulus even if intervals between electrodes are small. One or a plurality of electrodes of an array electrode formed from a plurality of electrodes are selected and connected to a current source to allow them to function as current source electrodes, a plurality of electrodes in the vicinity of the current source electrodes are alternately switched for connection to a current source and ground, a plurality of electrodes other than vicinity electrodes are connected to ground to allow them to function as ground electrodes, and current source electrodes and the ground electrodes are separated via vicinity electrodes to provide the step of electrically stimulating from current source electrodes and switch the current source electrodes in the above step at specified time intervals, whereby tactile sense is presented.
