The waterproof sheet also has an upper sheet also with the uneven surface, which has holes in the recesses on the surface. The upper and lower sheets are layered on each other and fastened with hooks, and the moisture of the enuresis or incontinence is made to fall into the recesses on the lower sheet to be reserved and sealed in between the upper and lower sheets, so that spreading of the moisture and wetting of the clothes of the sleeper caused by turning of the sleeper can be prevented.
