PROBLEM TO BE SOLVED: To provide a metallic net cage member for bulkhead construction capable of increasing quantity of a filling material to fill by forming an inner space large, consequently, maintaining natural environment by keeping favourable water permeability, improving workability at the time of construction and reducing construction cost of a bulkhead including transportation cost of a material. SOLUTION: Frame members 13, 15, 16 are arranged on a bottom member 11 free to oscillate by connecting the frame members 13, 15, 16 to the bottom member 11 doubly used as a cover member of a lower net cage through a connector 2, and sides of the frame members 13, 15, 16 are connected to each other through the connector 2. Consequently, metallic net cages 1A, 1B upper parts of which are opened are constituted, a filling material such as crushed stones, etc., is filled in these net cages 1A, 1B, and a bulkhead is constructed by accumulating them.
