A wire harness 10 has a sheathing material 21 that is flexible and covers wires 11, a path-regulating member 31 for regulating a path along which the wires 11 are arranged from outside of the sheathing material 21, the path-regulating member 31 having an axial direction parallel to the path along which the wires 11 are arranged, and an intermediate clamp 41. The intermediate clamp 41 has a support portion 51 for supporting the path-regulating member 31, and an attachment portion 61 with a ring-shaped structure for attaching the sheathing material 21. The attachment portion 61 has an insertion portion 62 that enables the sheathing material 21 to be inserted therefrom in a radial direction of the ring-shaped structure. The attachment portion 61 can be changed between an open orientation that enables the sheathing material to be inserted from the insertion portion 62, and a closed orientation that makes the ring-shaped structure into a continuous ring shape. The closed orientation is formed by locking structures, which include a first locking structure 63 and a second locking structure 64 that are arranged separately from each other in the axial direction of the ring-shaped structure.
