When a pulse current is applied to the coil 2, an instantaneous magnetic field fluctuation occurs in the first coil 2, thereby generating a magnetostrictive vibration wave in the area where the first coil 2 of the magnetostrictive transmission medium 1 is wound. This magnetostrictive vibration wave t propagates along the longitudinal direction at a propagation speed unique to the magnetostrictive transmission medium 1, and during this propagation, the electromechanical coupling coefficient of that part changes at the part of the magnetostrictive transmission medium 1 where the magnetostrictive vibration wave exists. Depending on the magnitude, mechanical energy r- is converted into magnetic energy ~, and an induced electromotive force is generated in the 21st coil 4.
