The interlaced part is provided with a low interlaced part (32) and a high interlaced part (31) on the front surface layer and the rear surface layer, and the high interlaced part is provided in approximately identical, corresponding locations on the front surface layer and the rear surface layer. In fibers of the front surface layer and the rear surface layer, the blending ratio of polyethylene terephthalate fibers is 80% or higher, and the fiber diameter of polyethylene terephthalate fibers is 3.3 dtex or more. The high interlaced part is formed to have an area ratio of 20-90% with respect to the surface area in a plane view of the front surface layer and the rear surface layer. The high interlaced part and the low interlaced part extend approximately perpendicular to a wiping direction of the dry sheet for cleaning, and are formed continuously alternating along the wiping direction.
