Patent ID: 8752232

Claim:
A cleaning sheet comprising: a substrate sheet; and a plurality of long-fiber bundles provided on at least one side of the substrate sheet, each said long-fiber bundle being made by aggregating long fibers oriented in substantially one direction, the long-fiber bundles being arranged side-by-side and joined to the substrate sheet, wherein: each said long-fiber bundle is formed by joining the long fibers together with a plurality of fiber-joining sections each extending linearly in a direction intersecting with the orientation direction of the long fibers, and each said long-fiber bundle is joined to the substrate sheet by a plurality of sheet joining sections; each said sheet-joining section is provided so as to overlap a portion of one of the fiber-joining sections; each said long-fiber bundle has been cut by a plurality of linear cut sections, each said linear cut section being formed in a region between adjacent said sheet joining sections which are adjacent to one another in the orientation direction of the long fibers, and each said long-fiber bundle includes cut fibers which are said long fibers that have been cut by the linear cut sections and also includes uncut fibers, which have not been cut, in the vicinity of the linear cut sections; and the substrate sheet is cut by the linear cut sections at the same positions as where the long-fiber bundles have been cut.
