ABSTRACT:
A film-coated wire is wound around a terminal at least one turn and pressed by an upper electrode of a resistance welding machine. A current is passed through the upper electrode when the wire is pressed, and heat is produced. The heat melts a film on the wire. The current is passed between the upper electrode and the lower electrode via the wire and the terminal to connect the wire with the terminal by resistance welding. A contact area between the wire and the terminal is increased by winding the wire around the terminal. Therefore, the wire is less likely to shift its position when a force is applied by the upper electrode. This increases reliability of the connection. Moreover, the terminal is reduced in size because it is not required to be formed in a U-shape.
