To provide an elevator cable and its manufacturing method and a wire and its manufacturing method, which can obtain high twist suppressing effect and requires no adjustment for remedying twist after being installed.SOLUTION: A tail cord 2 is formed by integrating a first and second wires 3 and 4, which are formed by twisting together multiple element wires 31 and 41, and a first to sixth aggregate wire cores 21-26 by extrusion molding of resin. The tail cord is manufactured by a hanging process to release rotating property of the first and the second wires 3 and 4 by hanging the first and second wires 3 and 4; and an extrusion molding process to hold the rotation direction position after the rotating property is released in the hanging process and implement the extrusion molding of the first and second wires 3 and 4 along with the first to sixth aggregate wire cores 21-26.SELECTED DRAWING: Figure 3
