PROBLEM TO BE SOLVED: To allow both emissive surfaces to drive by transverse vibration with the same amplitude everywhere which does not include longitudinal components at all. SOLUTION: At the central part in the longitudinal direction of a tool horn body 2 having an upper emissive surface 11 and a lower emissive surface 12 on the upper and lower edges, a first driving horn 4 to be driven by a first longitudinal oscillator 3, a second driving horn 6 to be driven by a second longitudinal oscillator 5, a third driving horn 8 to be driven by a third longitudinal oscillator 7, and a fourth driving horn 10 to be driven by a fourth longitudinal oscillator 9, are installed respectively. Upper slits 13a, 14a and lower slits 13b, 14b passing through in an orthogonal direction to longitudinal oscillation to be inputted are formed respectively between the respective driving horns 4, 6, 8, 10 and the respective emissive surfaces 11, 12 in the tool horn body. The oscillation of both the emissive surfaces 11, 12 is made into the transverse oscillation which does not include longitudinal oscillation by providing the respective slits 13a, 13b, 14a, 14b.
