Cleaning sheet

This cleaning sheet is provided with an embossed part in which the sheet is compressed in the thickness direction. The cleaning sheet is provided with outer layers, forming the surfaces of the sheet; and an inner layer sandwiched between the outer layers. In the boundary areas between the outer layers, and the inner layer, the fibers of the layers are entangled. This allows for a sheet that better retains the raised and sunken shapes embossed therethrough and exhibits excellent collecting performance.
