PROBLEM TO BE SOLVED: To attenuate vibration to a terminal in ultrasonic welding effectively with a simple configuration. SOLUTION: After a target electric wire 9 having the terminal 10 is set on an ultrasonic welding machine 3, the electric wire 9 is wound around a winding column 8 by one turn, and a winding section 12 is formed between the terminal 10 and an edge at a welded side. Then, a range including a crossing section 13 of the winding section 12 is held by a clamp 5, and the edge of the target electric wire 9 and that of another electric wire 11 are joined by the ultrasonic welding machine 3. In this case, since the winding section 12 is formed between the terminal 10 and the edge at the welded side for the target electric wire 9, vibration generated in welding is attenuated effectively by the winding section 12 and is hardly propagated to the terminal 10, thus preventing the terminal 10 from being broken.
