導体２と加圧することもできる。This pressing force is determined to a predetermined value by the physical properties such as the material and thickness of the band conductor 2 and the terminal 1 which are the target elements of the ultrasonic vibration bonding, and is set to the predetermined value. It is determined by the descending amount of the determined pressure drive mechanism. For example, the distance from the upper surface of the work mounting table 4 to the upper surface of the band conductor 2 (the surface with which the bonding tool 3 contacts) before the joining tool 3 presses the base 1a and the band conductor 2 in cooperation with the work mounting table 4. And the upper surface of the band conductor 2 from the upper surface of the work mounting table 4 after the joining tool 3 presses the base 1a and the band conductor 2 in cooperation with the work mounting table 4 (the joining tool 3).
And the distance between the base 1a and the band conductor 2 when the distance after pressurization is smaller than the distance before pressurization by a certain value. The relationship between the pressure and the descending amount is obtained by a correlation experiment between the pressure and the descending amount for checking whether the state is the state, and by using the descending amount, the joining tool 3 is cooperated with the work mounting table 4 in a predetermined manner. The base 1a and the band conductor 2 can be pressurized with the pressure described above. Further, a pressure sensor is provided in the pressurizing drive mechanism, and when the pressure sensor detects a predetermined pressure, the lowering of the pressurizing drive mechanism is stopped, and the pressurizing drive mechanism is controlled so as to maintain the stop position. Thereby, the joining tool 3 can press the base 1 a and the band conductor 2 with a predetermined pressure in cooperation with the work mounting table 4.

A booster or an ultrasonic horn is generated from a vibrator that is an electro-acoustic transducer or an electric vibration converter that includes a piezoelectric element or a magnetostrictive element that generates and outputs electrical energy that generates and outputs longitudinal wave ultrasonic vibration of a predetermined frequency. The ultrasonic vibration is transmitted to the joining tool 3 via the.
Then, the joining tool 3 resonates with the transmitted ultrasonic vibration and gives the resonated vibration (the direction of this vibration is the horizontal direction indicated by the arrow X) to the band conductor 2 from the outside for a predetermined time. Thereby, the resonance vibration of the joining tool 3 passes through the inside of the band conductor 2 from the outside of the band conductor 2 to join the plurality of band conductors, which are the components of the band conductor 2, with each other, and the band conductor 2 and the base 1a.

In the third embodiment, a case where the order of joining and swaging in the first embodiment is reversed is shown as an example. The joining tool 3 has an escape hole 3b that can accommodate the collapsed portion 8. Then, the portion of the stud 1b protruding from the band conductor 2 is crushed, and the crushed portion 8 is not in contact with the escape hole 3b in a state where the crushed portion 8 is clamped together with the base 1a and the crimping is completed. In addition, the annular tip surface around the relief hole 3a of the joining tool 3 presses the band conductor 2 around the crushed portion 8 with a predetermined pressure. In this state, the resonance vibration of the joining tool 3 joins the joint portions 5 from outside to inside of the band conductor 2.
