PROBLEM TO BE SOLVED: To provide a high-frequency oscillation horn which prevents coarsening of the crystals of the body of an ultrasonic horn, prolongs the lifetime of the whole of the horn and minimizes the influence on oscillation characteristics. SOLUTION: The high-frequency oscillation horn 10 amplifies the amplitude of high-frequency oscillations generated by a piezoelectric element 2 supplied with a high-frequency current and includes a base material 11 of the horn transmitting high-frequency oscillations generated by the piezoelectric element 2 and a screw chip 12 attached to the base material 11 of the horn in a freely removable way. There is formed a chip screw hole 13 for the screw chip 12 to be attached in a freely removable way to the end surface S2 of the base material 11 of the horn on the side where the high-frequency oscillations of the base material 11 of the horn are sent to the outside, and the screw chip 12 is fastened to the chip screw hole 13 so as to integrate the screw chip 12 with the base material 11 of the horn.
