<p>An ultrasonic horn used in, for instance, a bonding apparatus, being provided with a capillary attachment hole formed so as to be smaller than the capillary and a jig insertion hole that communicates with the capillary attachment hole. By way of inserting a jig into the jig insertion hole, the jig insertion hole is pushed open that causes the capillary attachment hole to be widened, so that the capillary is inserted and received in this enlarged capillary attachment hole. The capillary is fastened in place by the elastic force that is generated when the capillary attachment hole returns to its original shape, and the capillary is held in the horn main body without using any fastening tools.</p> |
