A cleaning sheet including a base sheet and at least one surface layer of filaments placed on the base sheet is described. The filaments extend in one direction and each of the filaments extends over the whole length of the surface layer in the extension direction of the filaments. The base sheet and the surface layers are bonded to each other at a plurality of bonding lines intersecting the extension direction. The surface layer includes a plurality of filaments-holding regions, each of which includes at least one end of the bonding line other than the bonding lines forming the filaments-holding region. Accordingly, in the filaments-holding regions, differences-in-level for collecting dust are formed and gaps (pockets) for capturing the dust therein are exposed.
