When applied to the drive surface 2 directly or indirectly through a fixed horn (not shown), the axial dimension L1 of the horn body 1 becomes
Since it is set to resonate at one wavelength, the radiation surface 3 side is displaced in the same phase as the drive surface 2 side.

きない。Therefore, the displacement of the radiation surface 3a of the outer horn 6 is as shown by a solid line graph X in FIG. 3, while the displacement of the radiation surface 3a of the inner horn 7 is the case where the hole 9 is not provided. Is as shown by a broken line graph Y shown in FIG. For this reason, if the minimum displacement that can be welded is at the level indicated by the symbol e in FIG. 3, welding cannot be performed using the radiation surface 3b.
