いかたいという問題かあった。(Problem to be Solved by the Invention) However, when assembling the conductor terminal portion of such a flexible wiring board with a terminal, the conductor terminal is inserted into a through hole of another wiring board, and then soldered. The main purpose is to obtain electrical connection between a flexible wiring board with one terminal and other wiring boards. For this reason, as shown in Figure 8, when the terminals of a flexible wiring board are formed in a linear shape, there is no way to prevent the flexible wiring board from coming off in any way. The terminal portion easily comes out from the through hole after the terminal portion is inserted and before soldering i=J is performed. For this reason, in the conventional technology, the terminal f=1
There was a problem in that it was difficult to connect the flexible wiring board to other wiring boards.

問題があった。In addition, as shown in Figure 9, if a bent part is formed by machining on the terminal part to prevent it from coming off, the bent part will prevent the terminal part from coming out of the through hole, but the terminal part will not come out from the through hole. The number of steps required to form the bent part during machining increases, which significantly increases the manufacturing cost.Due to the distortion of the machining process, the strength of the terminal part decreases, making it more likely to break with a small force. There was a problem.

で同時に行なうことが望ましい。As described above, the present invention provides a conductor terminal with a curved or bent portion, and this bent portion is formed by an etching method. In this case, the shape of the bent portion can be set arbitrarily, and the number of bent portions may be as long as one or more at any location on the conductor terminal. Furthermore, although it is of course possible to perform the terminal processing process independently, it is preferable to carry out the process simultaneously with the etching process during circuit formation of the flexible wiring board with terminals fζj.

It functions as a slip-off prevention part 44 for the through hole. As a result, once the conductor terminal is inserted into the through hole, the conductor terminal becomes difficult to come out from the through hole, making it easier to connect the terminal (=j) flexible wiring board to another wiring board.

As a result, the number of times the terminal broke was 2 to 5 times in the conventional machined product, whereas the number of times the terminal broke in the product of the present invention was 10 times or more. From this, it was confirmed that the terminal strength of the product of the present invention was several times higher than that of the conventional product.
