PURPOSE:To obtain a floating wave-dissipation structure for attenuating various waves effectively besides surface wave, by filling up a network-formed bag or a frame with many kinds of floating spheres of different specific gravity. CONSTITUTION:The inorganic specific-gravity-regulating material of pulverulent metal, sand, and others, and various synthetic resins are properly used to manufacture the plural kinds of the solid or hollow floating spheres 3a-c of different specific gravity in the range of the specific gravity of approx. 0.7-3. A network- formed bag 2, a metallic ring 4, and a frame consisting of rods 5 or the like are filled up with the many floating spheres 3a-c, and a floating wave- dissipation structure 1 is manufactured and permitted to float on the sea or the like. As a result, the various waves of horizontal wave, bottom wave, and the like besides surface wave can be attenuated.
