WIRE HARNESS AND WIRE HARNESS ROUTING STRUCTURE

It is an object to provide a wire harness for connecting a vehicle body-side device and a wheel-side device that can be routed in a small space appropriately, and can have an improved flex resistance. A wire harness for connecting a vehicle body-side device and a wheel-side device includes: a first wiring member; and a second wiring member that has higher flex resistance than the first wiring member. The first wiring member has an outer path length that is greater than an outer path length of the second wiring member.
