To obtain a cleaning sheet improved in an ability for cleaning the uneven parts of a surface to be cleaned, capable of gathering dusts having sizes in a wide range, preventing the gathered dusts or the self fibers of the non-woven fabric from dropping, and having a large sheet strength.
This cleaning sheet 1 is produced by arranging two kinds of thermally fusible short fibers having a fiber length of 5mm and different fiber diameters (fineness: 6d/f, 2d/f) into three-dimensional structures, respectively, by an air-laying method, thermally fusing the arranged products, respectively, to form two soft, bulky, suitably elastic and strong non-woven fabrics 2, 3, and subsequently combining the non-woven fabrics 2, 3 comprising two kinds of the different diameter thermally fusible short fibers in an arbitrary shape.
