To provide a marine structure unit which is easy and economical to construct for wave absorption and a marine structure.
A marine structure unit 1 is constituted by filling a large number of substantially sphere-like bodies 3 in a cage 2, which is easy to adjust an internal void volume. Preferably, the shape of the substantially sphere-shaped bodies 3 are completely spheric or ovally spheric for wave absorption. Preferably, at least the outermost layer of the substantially spheric bodies be formed with a polyolefin-based resin foam so as to enhance shock absorbing properties and durability. The units 1 can be set up in a marine area as a floating body. Preferably, the units 1 be floated by the buoyancy of the substantially sphere- shaped bodies. To adjust the buoyancy of the units 1, the substantially sphere- shaped bodies be integrally compounded with a polyolefin-based resin foam and a weight or the weight is mixed with the substantially sphere-shaped bodies and filled up in the cage 2, which makes it possible to lay out a heavy board- like body on the cage 2.
