Method for manufacturing fusing busbar

A method for manufacturing a fusing busbar, the method comprising:

• a disposing step of disposing wound second conductors and a wound first conductor formed of a different material from the second conductors;
• a rolling step of unwinding the first conductor and the second conductors and continuously feeding the first conductor and the second conductors to a rolling mill to press-weld the second conductors onto upper and lower surfaces of the first conductor to form a rolled joined plate;
• a cutting step of removing the second conductors of the rolled joined plate on the upper and lower surfaces of the first conductor to a predetermined width at a middle of the rolled joined plate to expose the first conductor;
• and a
• a forming step of press-forming the cut joined plate into a busbar shape to form the fusing busbar in which the second conductors are disposed on the upper and lower surfaces the first conductor on two opposite sides of the fusing busbar, and the first conductor is exposed in a middle of the fusing busbar.
