Abstract
An ultrasonic transducer includes a giant magnetostrictive rod 12 of a columnar shape which is made of a giant magnetostrictive member, and vibration plates 14 and 16 which are made of plate members having a larger diameter than that of the giant magnetostrictive rod 12 and are adhered and fixed to end surfaces in an axial direction of this giant magnetostrictive rod 12. The ultrasonic transducer can efficiently transmit ultrasonic vibration by expansion and contraction of the magnetostrictive rod in spite of a small and simple structure.
