The breakwater includes: a frame body having a plurality of supporting frames in which a number of coupling holes arc bored; a number of breakwater members in which combining holes are bored, and the coupling holes and the combining holes arc combined with each other by coupling elements; and front and rear supporters having respective fixing wires, connection linkages and heavy bodies.
