PURPOSE:The title conjugated fiber that is made by arranging the core and sheath layers of a thermoplastic synthetic polymer and an intermediate layer of an electrically conductive thermoplastic synthetic polymer under specific conditions, thus showing good fiber-forming properties, high conductivity and yarn quality. CONSTITUTION:A conjugated fiber is composed of the core layer A land sheath layer A2 of a thermoplastic synthetic polymer such as polyamide or polyester and the intermediate layer of a conductive thermoplastic polymer which consists of 15-20wt% of conductive carbon black and the same kind of a thermoplastic polymer as that of the core and sheath layer where the cross section of the sheath layer is less than 20% based on the total cross section area of the fiber, preferably less than 15%, further, the cross section of the intermediate layer occupies 5-30% and the sheath layer A1, 50-90% in total cross section.
