PROBLEM TO BE SOLVED: To provide a fiber product capable of obtaining good conductive performance even in surface resistance-measuring method and excellent in antistatic performance and endurance. SOLUTION: The method for producing a highly oriented and unstretched conductive conjugated fiber comprises carrying out melt-spinning of highly oriented yarn at≥2,000 m/min spinning rate so that a conductive thermoplastic component composed of a thermoplastic polymer containing carbon black has a conjugate structure covering≥50% fiber surface and the breaking elongation is≥80% and the shrinkage factor in 100°C hot water is≤20%. The present invention enables provision of fiber products excellent in antistatic performance and endurance. and enables adaptation to surface resistance-measuring method which plays a central role in Europe and the United States.
