PROBLEM TO BE SOLVED: To provide an interference current stimulation device capable of recognizing the position of generation of interference wave. SOLUTION: When two intermediate/high frequency currents crossing each other are fed between a first surface electrode 212a or 212b and a second surface electrode 221a or 221b, the cross point of the intermediate/high frequency currents is computed based on the result of transmission/receiving of ultrasonic waves between an ultrasonic transmission part 232a or 232b disposed near the first surface electrode 212a or 212b and an ultrasonic receiving part 241a or 241b disposed near the second surface electrode 221a or 221b.
