PROBLEM TO BE SOLVED: To provide an easily reusable lid for a slab hole, which can be simply attached to/detached from the slab hole, because the attachment and detachment of the lid or a water sealing implement for closing the slab hole against intrusion of rainwater etc. are conventionally troublesome. SOLUTION: This lid for the slab hole is equipped with an annular sealing member 22 which is installed on a top surface of a concrete slab in the state of surrounding a periphery of an opening of the slab hole 10 on the side of the top surface of the concrete slab C, and a lid member 21 for closing an upper part of the slab hole in the state of being placed on the sealing member so that the sealing member can be brought into close contact with the top surface of the concrete slab.
