The invention provides an ice melting wire and a fabrication method thereof. The ice melting wire comprises an electric conductor (2) and a carbon fiber core bar (5), wherein the carbon fiber core bar (5) comprises an electric conduction heating body (1) and a carbon fiber heat transfer layer (53) wrapping outside the electric conduction heating body (1), electric conductors (2) wraps outside the carbon fiber core bar (5), the electric conductors (2) and the carbon fiber core bar (5) are in electrical insulation, and the electric conduction heating body (1) and the electric conductors (2) are in electrical insulation. The fabrication method comprises the following steps of firstly, coating the outer surfaces of the carbon fiber core bar (5) and the electric conductors (2) with heat conduction coating layers (3); secondly, twisting the carbon fiber core bar (5) and the electric conductors (2) until the wire with required diameter and length is achieved; and finally, coating the outer surface of the wire with a hydrophobic coating layer (4). The ice melting wire has remarkable advantages of high strength, light weight, low sag, corrosion resistance and the like, an ice melting effect of ice coating of the wire can be achieved, and power failure is not needed.
