PURPOSE: A heating wire of a heat dissipation plate part is provided to efficiently transfer heat by forming a heat dissipation part at an outer sheath of the heating wire. CONSTITUTION: An electrical wire includes a heating line(1) corresponding to two strands of conductors which are made of a copper or metal alloy line. The wire includes an insulating layer(2), which is made of a hardening compound having a temperature control function, at an outer periphery thereof. A metal outer sheath(3) is made of a metal alloy including copper or nickel, etc at the outer periphery of the insulating layer. The metal outer sheath increases heat conduction efficiency and is automatically grounded even when the wire is damaged. A protrusion formed on the metal outer sheath increases heat conduction. The protrusion improves heat conduction in a specific direction. A radiation element of a spiral wing shape is formed to improve the heat conduction to in all directions. |
