PROBLEM TO BE SOLVED: To provide a duckboard provided on a balcony, covering a water drain pit connected with a guide groove for rainwater, and provided with a plurality of duckboards arranged at an interval each other and right and left support legs supporting the duckboards on a bottom face of the water drain pit to flow rainwater from the guide groove satisfactorily. SOLUTION: A duckboard 2 is provided with a plurality of duckboards 5 arranged at an interval each other and right and left support legs 6 having the duckboards 5 on a bottom face of a water drain pit 4, and a part facing a guide groove 3 of the support leg 6 is formed to be shorter than a width of the duckboard 2. Consequently, since the part facing the guide groove 3 of the support leg 6 is formed to be shorter than the width of the duckboard 2, rainwater can flow into the water drain pit 4 from the guide groove 3 satisfactorily without being blocked by the support legs 6 when rainwater flows therein from the guide groove 3.
