The length L of the flat wire harness 4 is determined by the connectors 5, 6 connected to both ends.
When the distance between the connectors 5 and 6 is long, it is necessary to use a flat wire harness with a long overall length L, while the distance between the connectors 5 and 6 is small. If the length is short, it is necessary to use one having a short overall length L. That is, if the length L of the flat wire harness 4 is shorter than the distance between the connectors 5 and 6, it cannot be used naturally. Conversely, if the length L of the flat wire harness 4 is too long than the distance between the connectors 5 and 6, an extra portion is generated in the flat wire harness, and the extra portion drips, causing other components to drop. There is also a danger that a short circuit will occur.
