<P>PROBLEM TO BE SOLVED: To provide a cleaning sheet and a cleaning tool, capable of effectively and uniformly wiping off dust even when the adhesion degree of a surface to be cleaned and the dust varies and capable of suppressing the formation of a fiber lump for a part of fibers used frequently for entangling and removing the dust. <P>SOLUTION: As the cleaning sheet 1, by folding and piling up fiber bundled bodies 11 in which many fibers 3 are arranged side by side and bonded in a direction crossing the flowing direction of the fibers 3 to form a bonding line 5, a folded part 4 extending along the flowing direction of the fibers 3 is formed, and the overlap structure of fiber layers 7, 7 connected at the folded part 4 and piled up with each other is formed. One part whose origin is at least the folded part 4 of at least one of the fiber layers 7, 7 piled up with each other is configured such that a distance from the bonding line 5 to the inner surface side ridge lines 13, 13 of the fiber layers 7, 7 is gradually different as separating from the folded part 4 along the extending direction of the bonding line 5 with the folded part 4 as the origin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
