A two-side cable-arrangement structure is disclosed. The two-side cable-arrangement structure includes a plate, a first cable-arrangement structure, and a second cable-arrangement structure. The first cable-arrangement structure and the second cable-arrangement structure are respectively disposed on two sides of the plate. A cable is fixed on the two sides of the plate by the first cable-arrangement structure and the second cable-arrangement structure simultaneously. Thereby, the cable is constrained at both the direction vertical toward the plate and the direction vertical away from the plate, and the fixed cable is not easy to move by pulling. It solves the difficulty of fixing a cable completely by a conventional single-side cable-arrangement structure in the prior art.
