PROBLEM TO BE SOLVED: To provide a method for generating an interference low-frequency for medical treatment by which interference vibrations can be generated by causing one set of oscillators composed of two independent oscillators to oscillate different frequencies and arranging the directors of the oscillators in parallel with each other. SOLUTION: In this method for generating the interference low-frequency, a pair of directors of the low-frequency oscillators having different frequencies are fixed in parallel with each other at a prescribed interval and the interference wave is generated at a prescribed depth in a prescribed extent by oscillating the directors.
