PROBLEM TO BE SOLVED: To provide a strand conductor for a movable part wiring material good in stranding, terminal working, having high conductivity, high tensile characteristics, high bending characteristics, and good high frequency characteristics, and provide a cable using this strand conductor. SOLUTION: This strand conductor for movable part wiring material 1 has double layered structure of an inner layer part and an outer layer part formed by twisting two or more kinds of strands having different mechanical characteristics, a first strand 11 for constituting at least the inner layer part 13 has tensile strength equal or larger than 1.5 times that of a second strand 12 constituting a part of at least the outer layer part 15, and the strands 11, 12 are twisted so that the ratio of the strength of the inner layer strand group constituting the inner layer part 13 to that of an outer layer strand group constituting the outer layer part 15 (inner layer strand group tensile strength/outer layer strand group tensile strength) becomes 0.5-5.
