Abstract
An ultrasonic transducer includes a giant magnetostrictive rodof a columnar shape which is made of a giant magnetostrictive member, and vibration platesandwhich are made of plate members having a larger diameter than that of the giant magnetostrictive rodand are adhered and fixed to end surfaces in an axial direction of this giant magnetostrictive rod. The ultrasonic transducer can efficiently transmit ultrasonic vibration by expansion and contraction of the magnetostrictive rod in spite of a small and simple structure.
