Abstract: A method for manufacturing a terminal-equipped electric wire is a method in which an exposed core wire of the electric wire is ultrasonically welded to a core wire connection portion of a terminal having a core wire connection portion and a coating crimping portion. The manufacturing method for the terminal-equipped electric wire including: supporting the core wire connection portion on an anvil; bringing the coating crimping portion into contact with a vibration suppressing contact portion; arranging the exposed core wire on the core wire connection portion and arranging the coating of the electric wire in the coating crimping portion; and ultrasonically welding the exposed core wire to the core wire connection portion in a state where the core wire connection portion is supported on the anvil and the coating crimping portion is in contact with the vibration suppressing contact portion.

Abstract: The present invention enables a core wire that contains a plurality of strands and a bonding object to be bonded more reliably using an ultrasonic bonding device that cantilever supports a pressing portion that performs ultrasonic bonding. A bonding object (for example, a terminal) is supported as on a stage, a core wire is overlaid on the bonding object, and the core wire and the bonding object are ultrasonically bonded in a state where the core wire is pressed toward the bonding object, using a pressing portion that is supported in cantilever fashion. During ultrasonic bonding, a pressing surface of the pressing portion is inclined in a pressing direction progressively toward a side where the pressing portion is cantilever supported, and also a bonding surface of the bonding object is inclined in the pressing direction progressively toward the side where the pressing portion is cantilever supported.

Abstract: An object is to allow an end portion of a core wire including a plurality of element wires and an object to be joined to be joined with as high a joining strength as possible. A joined product of a core wire including a plurality of element wires and an object to be joined includes a core wire including a plurality of element wires, and an object to be joined (e.g., a terminal) that has been ultrasonically joined to the core wire while being stacked on the core wire. The distance between a part of the core wire that has been joined to the object to be joined and a part thereof located opposite thereto gradually increases toward a distal end side of the core wire, at least partly in a direction in which the core wire extends.
