  • Patent number: 10128628
    Abstract: A method for manufacturing a terminal-attached electric wire including an electric wire including a core wire having plurality of strand wires, and a female terminal including wire barrels crimped around the core wire. The method includes a first step of applying ultrasonic vibrations to the core wire, and a second step of crimping the wire barrels in a region of the core wire to which ultrasonic vibrations have been applied. The first step includes applying ultrasonic vibrations to the core wire while leaving a compression margin for the crimping by the second step such that the resistance between the electric wire and the female terminal is stabilized until the strand wires of the terminal-attached electric wire are severed when the core wire of the terminal-attached electric wire is further compressed after the second step.
