PURPOSE: A heating cable for an electric mat is provided to improve the electric conductivity, the strength, and the durability of the cable by forming resistance heating lines with a plurality of wires and serially arrange the resistance lines. CONSTITUTION: A plurality of metal resistance wires is overlapped to form resistance heating lines. An insulating sheath material(120) covers the outer surface of the resistance heating lines. A conductive sheath material(130) covers the resistance heating lines which are covered with the insulating sheath material. A ground unit(140) is inserted into the conductive sheath material to a longitudinal direction. |
