PROBLEM TO BE SOLVED: To provide a conductive conjugate fiber using a polyester with little performance deterioration, producible by smooth spinning and drawing process, having uniform conductive performance in the length direction and having high conductive performance. SOLUTION: The conductive conjugate fiber is such that its conductive component consists of a conductive particle-containing copolymerized polybutylene terephthalate resin copolymerized with isophthalic acid (A) and/or adipic acid (B), wherein its(their) copolymerization amount(s) meet the formula (1) described below, and its nonconductive component consists of a fiber-forming polyester resin. In the cross section of the conjugate fiber, there are 3-20 conductive component open portions from the fiber surface to the vicinity of fiber center, these portions are joined together in the vicinity of fiber center, and the area ratio of the conductive component portions to nonconductive component portions is (1:9) to (5:5). The formula (1) is as follows: 5≤the copolymerization amount of A (mol%) + the copolymerization amount of B (mol%)≤55, wherein the copolymerization amount of A (mol%) is≤45.
