In the invention, metal substances are tightened integrally on both surfaces of one or plural sheets of electrostrictive element body (17) polarized in thickness direction and divided in two uniformly using a tightening tool thereby a flexible vibrator (10) is provided, and a cutting tool (33) is installed to an output end portion of the flexible vibrator (10) and a work is cut by ultrasonic vibration generated in the flexible vibrator. Workability of the cutting working is improved and the structure is simplified, and the device as a whole is made compact. |
