description PROBLEM TO BE SOLVED: To obtain a conductive composite fiber that is stably produced without troubles of end breakages in spinning and has excellent conductive performance by properly combining the melting points and the melt viscosities of a conductive component and a nonconductive component and to provide a method for producing the same. SOLUTION: In the conductive composite fiber obtained by bonding a conductive thermoplastic resin (resin A) containing conductive carbon black to a polyester-based thermoplastic resin (resin B) having a melting point of equal to or smaller than the melting point of the resin A+15°C, the ratio (ηa/ηb) of the melt viscosity (ηa) of the resin A to the melt viscosity (ηb) of the resin B is 0.4-2.5, the cross-sectional shape of a single filament is a shape in which the resin A is exposed to the surface of the filament in a rotational symmetry at two or more points and the boiling water shrinkage percentage is ≤12%.
