In this method, a ground wire 2 is overlaid on a shield wire 1 in cross. Next, overlapping portions of the shield wire 1 and the ground wire 2 are interposed between an upper resin tip 13 and a lower resin tip 14. By executing a first ultrasonic oscillation while inserting a projection 7a of an ultrasonic horn 7 into a through hole 13b of the tip 13, outside rinds 1d, 2b of the wires 1, 2 are removed in the vicinity of the overlapping portions. Next, by arranging a low-melting metal 15 and a resin piece 16 on a contact between the braided wire 1c and the core line 2a and executing a second ultrasonic oscillation, the contact can be brazed with the mutual welding of the tips 13, 14.

[ What is claimed is:] [1.]1. A method for connecting conductors of covered wires to each other, the method comprising:a first process including the steps of:preparing a first covered wire having a first conductor covered with an insulating cover and a second covered wire having a second conductor covered with another insulating cover;overlaying the second covered wire on the first covered wire so as to cross each other;putting overlapping portions of the first and second wires between an upper resin tip and a lower resin tip, the upper resin tip being provided, at a center thereof, with a through hole; andmelting and removing the insulating covers of the first and second wires in the vicinity of the overlapping portions by applying a first ultrasonic oscillation by inserting a projection of an ultrasonic horn into the through hole of the upper resin tip, thereby oscillating the overlapping portion with ultrasonic waves, directly; anda second process including the steps of:setting a brazing metal on a contact between the first conductor and the second conductor, the contact being exposed by removing the insulating covers of the first and second wires; andmelting the brazing metal to braze the contact by a second ultrasonic oscillation carried out by previously inserting the brazing metal into the through hole and sequentially inserting a resin piece into the through hole.
