    摘要: A stretchable laminated sheet with hydrophilic properties, which particularly has an excellent feeling and stability in wearing and is capable of efficiently enhancing the effect and efficacy brought about by a liquid component on a skin or other object, when the stretchable laminated sheet is impregnated with the liquid component and wet and then used on the skin or other object. A stretchable laminated sheet, which is obtained by partially thermocompression-bonding and laminating a hydrophilic short fiber layer extensible in at least one direction and an microfiber layer having a elastomer long fiber of a fiber diameter of 15 μm or less at 50% or more by weight, wherein discontinuous and regular concave and convex parts caused by the partial thermocompression bonding are formed on a surface of the hydrophilic short fiber layer that is exposed on one surface of the stretchable laminated sheet, the total area of the concave parts is in a range of 3 to 40% of the area of the surface of the hydrophilic short fiber layer, and at least the elastomer long fiber of the microfiber layer is softened and consequently joined to a fiber constituting the hydrophilic short fiber layer in a sheet thickness direction of a section where the concave parts exist, whereby the hydrophilic short fiber layer and the microfiber layer are integrated with each other.
