Abstract
Disclosed is a cleaning sheet having a cleaning surface side to be applied to an object to be cleaned. The cleaning surface has second regions along its longer sides and a first region between the second regions. In the first region, an exterior nonwoven fabric is exposed externally; in the second regions, a liquid permeable sheet having a lower density than the exterior nonwoven fabric is exposed externally. Liquid on a floor surface is allowed to pass through the liquid permeable sheet in the second regions and be absorbed by a liquid absorbent sheet. This prevents excess liquid between the exterior nonwoven fabric and the floor surface.
