In the above-mentioned wire harness formed by bundling a large number of electric wires, it is absolutely necessary to avoid short-circuiting with the electric wires that need to reliably prevent noise from entering or the vehicle body panel. Electric wires that need to be connected, such as a power line directly connected to a battery that always has a current flowing through a lamp system such as a headlamp when a key is inserted into a vehicle, an electric door lock system, etc., and a twisted electric wire for speakers, etc. It is preferable that the wire group be located at the center of the cross section and not located at the outer peripheral portion. That is, since a large amount of current flows in the power supply line,
It is preferable to locate at a center position where disconnection hardly occurs due to interference by a vehicle panel or the like. In addition, the more the twisted wire for a speaker is located at the center position, the more noise can be prevented.

However, in the conventional method of binding a wire harness shown in FIG.
