Disclosed is a conductive polymer which is easily dispersed in an organic solvent. A method of preparing the conductive polymer adapted to be dispersed in an organic solvent is also provided, which includes chemically polymerizing a monomer using as a dopant anion a phosphate-based compound having solubility in an organic solvent. The conductive polymer capable of being dispersed in various organic solvents can be obtained through a simple preparation process, and thus can be utilized in the fields of applied materials in which the use of conventional water-dispersible conductive polymers is limited.
