A wiring harness is provided with a first wire member including a first terminal and a first wire and a protector for accommodating the first wire member. The protector includes a protector body, a bolt and a restricting portion. The protector body has a bottom wall extending in a length direction, two side walls projecting from both side edges of the bottom wall and facing each other, and an opening formed by the two side walls and facing the bottom wall. The bolt projects from the protector body and is inserted into a through hole of the terminal. The restricting portion covers only a part of the first wire member closer to a side opposite to a tip side of the first terminal than the through hole in the length direction, and restricts a movement of the first wire member in a projecting direction of the bolt.
