PROBLEM TO BE SOLVED: To provide a multicore unshielded twisted pair cable of which, respective twisted pair cables have unified signal propagation properties (signal transmission rate, as well as wave form) between themselves, time skew is made to become very small, and wave form correction is enabled to perform with an identical circuit. SOLUTION: The number of pitch n (turns/m) is made to smoothly change, and the number of pitch n (turns/m) in average at respective twisted pair cables are made to become identical with each other, and respective cables are made to be adjacent with each other with different pitch.
