動搭載が困難になるという欠点がある。In the conventional flexible printed circuit board sheet described above, since only the reinforcing substrate 7 supports the flexible printed circuit board body 1, the surface mount component 9 is automatically mounted on the first cover film 4 of the flexible printed circuit board body 1. In the case of mounting with, the bending and bending of the soft three-layer structure are likely to occur in the portion where the hard reinforcing substrate 7 is not adhered. That is, the portion without the hard reinforcing substrate 7 is soft, and the mounting position of the component 9 is likely to shift due to bending or bending of this portion. Therefore, there is a drawback in that the positional accuracy of the substrate is deteriorated and it is difficult to automatically mount the components.
