Abstract
The present invention relates to a conductive polymer composition for a PTC element with decreased NTC characteristics, using carbon nanotubes, a PTC binder resin, and a cellulose-based or polyester-based resin for fixing the carbon nanotubes and the PTC binder, and to a PTC element, a circuit and a sheet heating element using the same.
