PROBLEM TO BE SOLVED: To provide a method for mutual connection between flexible printed boards which can reduce the manufacture cost by securely connecting terminals of the flexible printed boards to each other. SOLUTION: Wires 16 and 26 are formed on insulating films 15 and 25 as the bases of FPC's 10 and 20, and a cover lay is formed on the insulating films 15 and 25 and wires 156 and 26 except parts which become the terminals 11 and 21 to manufacture the FPC's 10 and 20. After the terminal parts 11 and 21 of the FPC's 10 and 20 thus prepared are folded to the reverse surface sides of the insulating films 15 and 26, the wires 16 and 26 are brought into contact with each other. Further, temporary crimp contact processing is performed by pressing them from the sides of the insulating films 15 and 25. In this state, electrodes 9a and 9b of a series welding device (not illustrated) are made to abut from above the wires 16 and 26 of the respective terminal parts 11 and 21, and a specific voltage is applied to join the wires 16 and 26 together. |
