<p>Provided is a wire harness which enables at least part of a mark formed on the outer surface of a covering portion to be prevented from peeling off and an electric wire to be identified. A wire harness (1) comprises an electric wire (2) and a connector (3). The electric wire (2) is provided with a conductive core wire (21) and an insulating covering portion (22) for covering the core wire (21). The connector (3) is attached to the end portion (2a) of the electric wire (2) and houses the end portion (2a) of the electric wire (2) therein. A first mark (6) and a second mark (7) are formed on the outer surface (22a) of the covering portion (22) of the electric wire (2). The first mark (6) is formed by coloring part of the outer surface (22a) of the covering portion (22) of the electric wire (2) housed in the connector (3) in a color (A) different from the single color (N) of the outer surface (22a). The second mark (7) is formed by coloring part of the outer surface (22a) of the covering portion (22) of the electric wire (2) exposed to the outside of the connector (3) in the same color (A) as that of the first mark (6).</p>
