PROBLEM TO BE SOLVED: To provide a breakwater having a relatively simple structure so that an exchange of seawater between inland sea and open sea is smoothly carried out and using an excessive quantity of rubble mounds is prevented while it is aimed to construct the breakwater quickly and also at a low cost. SOLUTION: The skeleton type break water is constructed by at least one unit structure, which is composed of a rubble-mounded stylobate (12), a lower slab (13), a plurality of vertical pillars (20), many slanting pillars (14), an upper slab (15), a front face wall (16) with many seawater flow holes (18) on one side (sea-side), a rear face wall (17) on the other side, and a concrete cap (19) which is provided on an upper surface of the upper slab (15) by placement and curing at the construction site.
