1. A wire harness comprising:
a wire;
a positioning member that is made of a synthetic resin and is provided on an outer circumference of the wire;
a ring-shaped electromagnetic wave absorber that has a through hole through which the wire passes and is fixed to the positioning member; and
a fixing member for fixing the positioning member to the wire, wherein:
the positioning member includes:
a main body including an insertion portion inserted in the through hole,
a fixing portion protruding from the main body to an outside of the through hole, and
a first protrusion that protrudes from an outer surface of the insertion portion in a radially outward direction, such that, when the insertion portion is inserted in the through hole of the electromagnetic wave absorber, the electromagnetic wave absorber extends further radially outward than the first protrusion,
the fixing member is formed so as to fasten the wire and the fixing portion to each other,
the main body has a tubular shape through which the wire passes,
the main body has a slit that extends in an axial direction of the main body,
the positioning member has a second protrusion that protrudes in a direction intersecting the axial direction from the outer circumferential surface at an end on a side opposite to the fixing portion out of the ends in the axial direction of the main body,
the second protrusion opposes a second side surface of the electromagnetic wave absorber,
the second protrusion is formed such that an amount of protrusion from the outer circumferential surface of the main body decreases as a distance from the electromagnetic wave absorber increases,
the second protrusion is in contact with the second side surface of the electromagnetic wave absorber, and
the outer circumferential surface of the second protrusion at the portion in contact with the second side surface is formed so as to be flush with the outer circumferential surface of the electromagnetic wave absorber.
