A liquid-retaining sheet contains a liquid-retaining layer that is able to absorb a liquid component, and the liquid-retaining layer is formed from a nonwoven structural member containing a transparent fiber. In the liquid-retaining sheet, the transparency shown below is adjusted to not more than 0.27. Transparency=Whiteness (%) of a sheet impregnated with 700% by mass of water relative to the sheet mass/Basis weight (g/m2) The transparent fiber may contain a cellulose-series fiber substantially free from a carboxyl group (in particular, a regenerated cellulose fiber such as a solvent-spinning cellulose-series fiber). The proportion of the solvent-spinning cellulose-series fiber may be not less than 30% by mass in the transparent fiber. The liquid-retaining sheet may be a skin care sheet (in particular, a facial mask) that is impregnated with a liquid component containing a cosmetic preparation. The liquid-retaining sheet has an improved transparency in a wet state in spite of a nonwoven structural member contained in the sheet and shows a suitable strength in a wet state.
A liquid-retaining sheet comprising a liquid-retaining layer that is able to absorb a liquid component and an adhesion layer over a side of the liquid-retaining layer,
