摘要： A heating device for an electric vehicle, according to an embodiment of the present invention, comprises: a water pump which is for circulating supplied water; a heating resistor which has one or more surface type heating elements formed by means of a heating paste composition and is for heating the circulated water; a water temperature sensor which is for measuring the temperature of the hot water heated by means of the heating resistor; and a control unit which is for adjusting the heating resistor such that the measured temperature measured by means of the water temperature sensor satisfies a set temperature value, wherein the heating paste composition comprises, on the basis of 100 parts by weight of the total heating paste composition, 3˜6 wt % of carbon nanotube particles, 0.5˜30 wt % of carbon nanoparticles, 10˜30 wt % of a mixed binder, 29˜83 wt % of an organic solvent, and 0.5˜5 wt % of a dispersant, wherein the mixed binder has epoxy acrylate, polyvinyl acetal and phenolic resin mixed therein or has hexamethylene diisocyanate, polyvinyl acetal and phenolic resin mixed therein.
