SOLUTION: The revetment/bed protection construction member includes a wooden frame 2 and partition boards 8 mounted to the frame 2. The frame 2 comprises longitudinal pieces 3 set at every predetermined interval and crosspieces 6 combined with both ends of each longitudinal piece 3, and each partition board 8 is provided between the longitudinal pieces 3 and 3 adjacent to each other at every predetermined interval to form a narrow space 9 between the partition boards 8 adjacent to each other. Natural purification capacity can be provided to a river, a lake, a marsh or the like by purifying action of the frame and the partition boards 8. The revetment/bed protection construction member is provided to a levee, the bottom of the river, the bottom of the lake or the like to enable the part thereof to form undulations. Since the environment for the living thing to live at ease can be formed, the adverse influence on the ecosystem can be prevented, and the destruction of the natural environment can be prevented.
