The present invention relates to a conductive polymer composite, a method for manufacturing the conductive polymer composite and an electrode active material for a secondary electrode including the conductive polymer composite. The present invention provides the method for manufacturing the conductive polymer composite, comprising the steps of: mixing aniline with a substituent, aniline, a solvent and a filler to manufacture a mixture; adding dropwise an initiator and dopants to the mixture to manufacture emeraldine salt polyaniline (PANI-ES) copolymer; stirring the emeraldine salt PANI-ES copolymer in a basic aqueous solution to manufacture emeraldine base polyaniline (PANI-EB) copolymer; and adding inorganic materials to the emeraldine base PANI-EB copolymer to perform a doping operation to manufacture a conductive polymer composite. The present invention induces expansion of polymer chains to have conductivity and at the same time enhances compatibility with matrix materials. 전도성 고분자 복합체, 상기 전도성 고분자 복합체의 제조 방법, 및 상기 전도성 고분자 복합체를 포함하는 이차 전지용 전극 활물질에 관한 것이다.
