PROBLEM TO BE SOLVED: To allow a user to sufficiently sense a feeling of stimulation of a medium frequency while effectively using advantages by an interference low frequency. SOLUTION: When a stimulation current, for example 5,000 Hz, is fed from a first sine wave generation circuit 11 to a first group of electrodes, or a pair of two electrodes, 1A and 1B and a stimulation current, for example 5,020 Hz, is fed from a second sine wave generation circuit 12 to a second group of electrodes, or a pair of two electrodes, 2A and 2B, this electric stimulation device is defined as a first mode providing the stimulation of the low frequency by interference. When the same stimulation current, for example 5,000 Hz, is fed from the first sine wave generation circuit 11 to the respective groups of electrodes 1A, 1B, 2A and 2B, this electric stimulation device is defined as a second mode providing the stimulation of the medium frequency alone. The first mode and the second mode are alternately repeated. COPYRIGHT: (C)2010,JPO&INPIT
