<P>PROBLEM TO BE SOLVED: To obtain continuous stimuli with more sense of continuity in the direction of an array of electrodes, with respect to a multi-channel electrical stimulator having n pairs of electrodes. Ž<P>SOLUTION: N output parts for outputting sine wave current equal to 1000 Hz or larger are provided with a modulation part for applying amplitude modulation or frequency modulation to output of the respective output parts. A modulation signal outputted by the modulation part radically makes an amplitude I0 of the sine wave current of a fixed amplitude outputted by the output part zero or a small value close to zero; then the amplitude is increased during a period T1; a maximal value of the amplitude is made larger than an original fixed current; it is returned to the original fixed output; outputs of the respective output parts are successively modulated, and continuous moving stimuli are obtained by partially overlapping outputs whose parts stimulated more strongly by modulation are adjacent.
