Zusammenfassung: | This wiping sheet (1) includes a fiber aggregate (1A) that has on at least one surface thereof an uneven section having a macroscopic pattern, and that contains irregular fibers having a flat shape in a transverse cross-section. In recesses (3) and protrusions (4) that constitute the uneven section, the transverse cross-section long diameter of irregular fibers (2) present in the recesses (3) is largely facing in a direction along the surface of the wiping sheet (1), and the transverse cross-section long diameter of irregular fibers (2) present in the protrusions (4) is largely facing in a direction along a surface which is orthogonal to the surface of the wiping sheet (1). |
