摘要： A magnetostrictive transducer generating a torsional wave in a subject having a predetermined section and measuring a torsional wave propagating in the subject. In the magnetostrictive transducer having a ferromagnetic patch attached to a predetermined position of a subject, a cylindrical insulator installed around the periphery of the ferromagnetic patch, and a coil wound around the cylindrical surface of the insulator, a torsional wave is generated based on a magnetostrictive effect to then be induced to the subject when current is applied to the coil. The ferromagnetic patch includes a strip unit attached to the subject in an inclined manner with respect to an axial direction of the subject and transferring the torsional wave to the subject; and tail units formed at opposite ends of the strip unit and concentrating a magnetic flux on the strip unit when current is applied to the coil.
