PROBLEM TO BE SOLVED: To precisely predict a time of disconnection of a robot cable and properly determine the time of replacement. SOLUTION: In the robot cable 10 used for an electrical connection to movable parts 2 and 3 of a robot, a plurality of disconnection detecting core wires 13 to 15, whose mechanical lives are respectively different and shorter than the mechanical lives of main core wires 11 and 12 are integrally arranged, with the main core wires in the cable along a direction of length. Each of the disconnection detecting core wires 13 to 15 which has one end arranged in the same side and the other end formed with transmitting lines 13a to 15a and receiving lines 13b to 15b, which are respectively electrically connected in pairs.
