Provided are a cooling device coated with carbon nanotubes and method of manufacturing the same. Carbon nanotubes are dispersively coated on a surface of the cooling device that radiates generated by a predetermined apparatus or component through thermal exchange. Thus, a carbon nanotube structure is formed so that the cooling device can improve in a thermal radiation characteristic and become small-sized. As a result, electronic devices can be downscaled and heat generated by a highly integrated electronic circuit chip can be effectively radiated, thus increasing lifetime and performance of an operating circuit.
