PROBLEM TO BE SOLVED: To solve such a reliability problem of a flexible board having a branch structure of prior art that decrease in adhesive force proceeds due to a force for unbending and opening a bend, after two bodies are folded and fixed in an adhesion region, and the adhesive portion end is peeled to cause a gap, and to solve such a problem that in the soldering process of two bodies, position of the electrode of the body soldered earlier is deviated due to reheat at the time of soldering the body to the second.SOLUTION: A novel flexible board having a brach structure is provided. The flexible board includes a first body and a second body coupled mutually, where one body has a structure capable of folding the whole flexible board in the longitudinal direction. At the tip of two bodies, a plurality of electrodes are provided, respectively. The plurality of electrodes are connected, by soldering, to the positions substantially corresponding to the opposite sides of a target printed board ends, respectively. In the plurality of electrodes of two bodies, peeling stress caused by the folding is applied along the long side of individual electrodes.SELECTED DRAWING: Figure 4 |
