The number of man-hours for fixing to and the man-hour for parts management are further simplified.

  On the other hand, the connecting portion of the flat electrical component has a frame portion that forms a through hole through which the belt member is passed, and a conventional belt member for bundling electric wires integrated with the belt holding portion is adopted. It is also conceivable. In this case, a conventional belt member for binding electric wires, which is a general-purpose product, can be effectively used.
