Disclosed is a cable tie used for the purpose of tying and arranging cables, and it is formed of a belt part 310 which is stored in the shape of a reel 370 at usual time and is unwound for tying cables when needed, and engaging head parts 320 and 420 fixing and preventing the belt part, which has tied the cables, from loosening. The present invention makes it possible to conveniently arrange the cables without using a special tool, and over consumption of the belt part can be prevented as compared to a conventional cable tie 100 in which the leftovers of the belt part 130 after it is cut are discarded. In case of the conventional cable tie 100, the cable tie 100 should be used depending on the thickness of the cables to be arranged; however in the present invention, the belt part 310 is unwound as much as the needed length long enough to tie the cables, and the cables are tied, and the belt part 310 is tightened and cut, and the remaining leftovers are wound on the reel 370 and are stored. So, it does not need to carry various types of cable ties during the cable arranging work, and the leftovers of the belt part 310 can be effectively stored.
