摘要：
A laminated sheet is produced by forming an adhesion layer permeable to a liquid component and contactable with a skin on at least one side of a liquid-retention layer comprising a nonwoven structural member and having an ability to absorb the liquid component. The adhesion layer comprises a nonwoven structural member comprising a fiber having a number-average fiber diameter of not more than 10 μm, and the thickness ratio of the adhesion layer relative to the liquid-retention layer is 1/4 to 1/100 as a ratio of the adhesion layer/the liquid-retention layer. The fiber of the nonwoven structural member of the adhesion layer may have a standard deviation of fiber diameter of not more than 5. The nonwoven structural member of the liquid-retention layer may comprise a fiber having a fiber diameter larger than that of the fiber of the adhesion layer. The laminated sheet has a liquid retentivity and a liquid releasability in a well-balanced manner, and has an excellent adhesion and an excellent fit to the skin in the state where the sheet is impregnated with a liquid component.
