PROBLEM TO BE SOLVED: To provide a laminated sheet having high water absorbency and leaving little liquid when wiping a wet object therewith. SOLUTION: The laminated sheet comprises a hydrophilic fiber layer and micro fiber layers set on the both surfaces of the hydrophilic fiber layer, wherein the micro fiber layers contain micro fibers having≤0.9 dtex fineness and, in the hydrophilic layer, the hydrophilic fibers are at least partially bonded to each other, and the laminated sheet is obtained by laminating fiber webs on the both surfaces of a hydrophilic nonwoven fabric or a hydrophilic filament layer to form the laminate, wherein the fiber webs contains≥50 mass% splittable type conjugated fiber, the hydrophilic nonwoven fabric contains≥20 mass% hydrophilic fibers and point-bond regions or interlacing fiber regions and the hydrophilic filaments of the hydrophilic filament layer are at least partially self-bonded to each other, and treating the laminate by a water race interlacing method to split the splittable fibers to obtain micro fibers having≤0.9 dtex fineness and to integrate the hydrophilic nonwoven fabric with the micro fiber layer.
