摘要： Disclosed is a moisture-retaining body (10) having a water-absorbing surface (11), having a structure in which, from a water-absorbing surface (11) side, a water-permeable layer (12) having water disintegrability and water permeability, a moisture-retaining layer (13) having water disintegrability, water absorbability, and water retainability, a water-repellent layer (15) including a water-soluble film (14) and dots of a dot-like water-repellent resin with a diameter of 5 pm to 150 pm dispersed on a surface side of the water-soluble film (14) facing the moisture-retaining layer (13), and a support layer (16) having water disintegrability are sequentially laminated, as a moisture-retaining body which is quickly dissolved or decomposed by coming into contact with a large amount of water when dumped in a flush toilet or the like while being prevented from being dissolved or decomposed by retained moisture.
