<p>PROBLEM TO BE SOLVED: To provide a terminal structure of a flexible substrate capable of joining a terminal reinforcing plate simultaneously when joining the flexible substrate with a connection terminal, and a manufacturing method thereof. SOLUTION: The terminal reinforcing plate 9, an FPC 4, and the connection terminal 1 overlap in this order, electrodes 10a and 10b are allowed to abut thereon from a top side of a joining end 3 of the connection terminal 1, and a large current of the capacity used for the resistance welding is allowed to flow therein. The connection end 3 is joined with a contact surface 13a of a wire 6 of the FPC 4 by the generated thermal energy by the energization. At the same time, a part of an insulating film 5 of the FPC 4 is also melted by the generated thermal energy to form a welded part 12 at a contact surface 13b of the insulating film 5 with the terminal reinforcing plate 9. The welded part 12 is cooled and solidified to form a joined part 8, and the connection terminal 1, the FPC 4 and the terminal reinforcing plate 9 are joined with each other. The terminal reinforcing plate 9 is simultaneously welded in the joining process of the connection terminal 1 to the FPC 4.</p> |
