The fixing tool (40) of a wire harness (32) bundling a plurality of cables has a portion (42) for holding the wire harness (32), and two protrusions (44) protruding therefrom. The protrusion (44) includes a stretching portion (46) formed by stretching. Since the length from the base face (48) of the holding portion (42) to the stretching portion (46) is different in different protrusions (44), the timing at which each stretching portion (46) is inserted into a through hole (56) varies and thereby insertion load of the protrusion (44) can be reduced. Consequently, workability of a work for securing the wire harness (32) to a bracket (54) can be improved.
