A wire harness includes an electric wire portion in which three electric wires are collected in the same direction, a braided wire which surrounds the outer circumferential side of the electric wire portion in a bundle, and an electric wire holding member which maintains the arrangement of the electric wires about a center axis line of the electric wire portion. The electric wire holding member includes a plurality of braided correction portions which protrudes in the direction of the center axis line from an inner circumferential surface of the outer shape holding portion between two adjacent electric wires of the electric wire portion in the circumferential direction about the center axis line, and is formed so that the braided wire approaches the center axis line in relation to outer circumferential tangential lines connecting conductor portions of the two electric wires in a cross-section perpendicular to the center axis line.
