A two-side cable-arrangement structure (5) is disclosed. The two-side cable-arrangement structure (5) includes a plate (52), a first cable-arrangement structure (54), and a second cable-arrangement structure (56). The first cable-arrangement structure (54) and the second cable-arrangement structure (56) are respectively disposed on two sides (522,524) of the plate (52). A cable (6) is fixed on the two sides (522, 524) of the plate (52) by the first cable-arrangement structure (54) and the second cable-arrangement structure (56) simultaneously. Thereby, the cable (6) is constrained in both the directions vertically toward and away from the plate (52), and the fixed cable (6) is not easy to be moved by pulling. It solves the difficulty of fixing a cable (2) completely by a conventional single-side cable-arrangement structure (1, 3) in the prior art.
