A wire harness includes a linear trunk line section formed by bundling a plurality of power supply lines serving as linear wiring bodies wired in a vehicle and a pair of trunk line end distributors each of which is connected to a corresponding one of both ends of the linear trunk line section and distributes electric power from a power supply mounted on the vehicle to each connected appliance, the power supply being connected to at least one end of each of the trunk line end distributors. Thus, with the wire harness, a wiring path can be simplified by combining the linear trunk line section and the pair of trunk line end distributors.
