PROBLEM TO BE SOLVED: To provide a method for producing a conductive conjugate fiber, by which the conductive conjugate fiber containing conductive particles such as conductive carbon black or metal powder and having practically sufficient characteristics can stably be produced by a one step high speed spinning method. SOLUTION: This method for producing the conductive conjugate fiber, comprising polybutylene terephthalate resin containing conductive particles as a thermoplastic resin as a conductive component and a fiber-forming polyester-based resin as a non-conductive component, is characterized by melt-spinning the conductive component as a core component and the non-conductive component as a shear component with a bi-component spinning machine, cooling and solidifying the spun fiber, and taking off the solidified fiber at a rate of 4,000 to 5,000 m/min to obtain the conductive conjugate fiber having an electric resistance of≤1×10<SP>8</SP>Ω/cm and a boiling water shrinkage factor of≤10%.
