PROBLEM TO BE SOLVED: To increase transmission efficiency of ultrasonic vibration when a capillary is exchanged, obtain excellent reproducibility and improve the life of an attaching part of an ultrasonic horn. SOLUTION: A plurality of metal bushes 2 which are circularly protruded are uniformly arranged on a peripheral wall of a fixing hole 1 of a horn 3 in which a capillary 4 is inserted and fixed. The capillary 4 is clamped and retained with the horn 3 via the metal bushes 2. Even if the capillary 4 has unevenness on the surface and irregularity in the outer dimension, a large number of point contacts or line contacts with an ultrasonic horn can be obtained in response to the irregularity of dimension or the unevenness of the capillary 4. |
