Abstract
The present invention is directed to connection technology for providing a sufficient connection strength in bonding a wire material and a twisted wire each having a large diameter when directly bonding the wire material, which is used for a stator of an electric motor and a generator, and the twisted wire serving as a lead wire by ultrasonic bonding. A twisted wire having a plurality of core wires is hardened by ultrasonic vibration using a pressurized vibration tool when the twisted wire is connected to a wire material. After that, the twisted wire is reversed such that the hardened surface thereof faces the wire material and then comes into contact with the wire material. In this state, ultrasonic waves are applied to the hardened surface from the opposite side using the vibration tool, thereby connecting the hardened surface of the twisted wire and the wire material.
