A wire harness includes a wire portion formed by arranging three wires in the same direction, the respective wires having conductors and insulators coating outer circumferences of the conductors, and a braided wire. The three wires of the wire portion and the braided wire are disposed such that the braided wire is interposed between two wires of the wire portion adjacent to each other along a circumferential direction around a central axial line of the wire portion on a cross section of the wire harness when viewed from an axial direction along the central axial line, on a side of the central axial line from outer circumferential-side tangents connecting the conductors of the two wires.
