PROBLEM TO BE SOLVED: To provide a tidal wave sluice enabling the saving of cost and time, less constrained with respect to site location, securely functioning, not providing risk to an operator, and suppressing adverse effect on river flows, industrial activities, landscape, and growing environment for living organism. SOLUTION: A river floor near the mouth of a river is formed smooth to use it as a foundation for a tidal wave sluice. A plurality of water cut-off boards having swing support parts installed on the upstream side of the foundation placed on the river floor and swing support parts combined with the swing support parts are arranged parallel with each other in a direction crossing the flow of the river. The tidal wave sluice comprises a water cut-off board raised attitude holding mechanism stabilizing the water cut-off boards when the water cut-off boards are raised and a water cut-off board connection mechanism loosely connecting the adjacent water cut-off boards to each other.
