PROBLEM TO BE SOLVED: To provide a technology for improving heat radiation performance from an outer peripheral surface of a conductive part in an electric wire.SOLUTION: An electric wire 10 is formed as pipe-shaped, and includes a conductive part 20 in which an outer peripheral surface 21 and an inner peripheral surface 23 form irregularities and a non-conductive jacket part 30 covering the outer peripheral surface 21 of the conductive part 20. The outer convex surface 212 of the outer peripheral surface 21 and the inner concave surface 231 of the inner peripheral surface 23 in the conductive part 20 are formed at a position of correspondence of the front and the rear (position of superimposing in the inside to outside direction), and the outer concave surface 211 of the outer peripheral surface 21 and the inner convex surface 232 of the inner peripheral surface 23 in the conductive part 20 are formed at a position of correspondence of the front and the rear (position of superimposing in the inside to outside direction). |
