WIRE HARNESS AND METHOD OF MANUFACTURING WIRE HARNESS

A wire harness includes: an electrical wire including a core wire and an insulating covering for covering the core wire; and a sheet material in which the electrical wire is disposed on a resin main surface, and a part of the main surface having contact with the electrical wire is welded to the insulating covering of the electrical wire, thereby forming an electrical wire fixing part. A thickness dimension of a first covering part in the insulating covering on a side of the electrical wire fixing part in relation to the core wire is formed smaller than a thickness dimension of a second covering part located on an opposite side of the core wire.
