Abstract: Proposed is a method of manufacturing a PTC heating element, the method including: (a) preparing a mixed powder of a polymer powder and a carbon nanotube-containing powder, (b) forming the mixed powder into a pellet-shaped body, and (c) extruding the pellet-shaped body to produce a wire-type heating element. A PTC heating element manufactured by the method is also proposed. The PTC heating element manufactured by the method has better thermal conductivity than existing PTC heating elements, so that the PTC heating element exhibits a quick temperature rise within a short time, resulting in a reduction in power consumption. In particular, when the PTC heating element is used as a heating element for car seat heaters and steering wheel heaters in electric vehicles, battery consumption may be dramatically reduced, contributing to an increase in the driving mileage of the electric vehicles.
