The present invention relates to a method for preparing a transparent electrode using a carbon nanotube(CNT) film, and more particularly, to a method for preparing a transparent electrode, the method comprising the steps of forming a CNT film on a desired substrate using a dispersed solution of CNT and then reducing/forming metal nanoparticles on the surface of the CNT film. According to the present invention, a transparent electrode in which gold nanoparticles are formed on the surface of high density CNT film having high purity, can be prepared. The inventive transparent electrode has high visible ray penetration and an excellent electrical conductivity by hyperfine metal particles uniformly formed on the surface thereof as well as a uniform increase in electrical conductivity over the whole CNT film, and thus it can be applied to various displays as well as image sensors, solar cells, touch panels, digital papers, electromagnetic shielding agents, static charge preventing agents and the like.
