A dry sheet for cleaning includes fiber layers, each arranged in front and back surface layers, and a nonwoven fabric layer between the fiber layers. The fiber layers are interlaced with the nonwoven fabric layer in an interlaced part which includes slightly interlaced parts and highly interlaced parts. The highly interlaced parts in the front surface layer are formed at almost same spots as those in the back surface layer. The front and back surface layers each include polyethylene terephthalate fiber having a diameter of 3.3 dtex or more at a rate of 80% or more. An area ratio of the highly interlaced parts to the front and back surface layers is 20 to 90%. The highly and slightly interlaced parts each extend in a direction almost perpendicular to a wiping direction of the sheet and are formed alternately and successively in the wiping direction.
