PROBLEM TO BE SOLVED: To provide a wet sheet for cleaning allowing the whole of cleaning faces to be effectively utilized and a cleaning movement to be stable. SOLUTION: The wet sheet for cleaning consists of a laminated sheet having a structure of at least three layers comprising an inner layer and nonwoven fabric layers disposed on both sides thereof and impregnated with specified amounts of an aqueous detergent. Each of layers except the inner layer is connected to each other at a peripheral part of the laminated layer and in inner positions beyond the peripheral part of the laminated layer as well to form each of connection parts. The rupture strength of the inner layer is 400 cN/20 mm or more in a state where the laminated sheet is impregnated with water of 500 wt.% to a dry weight of the laminated sheet before impregnation with the aqueous detergent.
