The cleaning process is the same as in the first embodiment. 2) Measurement of dust generation was as follows. Two pieces of interleaving paper were cut out into A4 size, and the cut out interleaving papers were overlapped and rubbed with both hands in a cube having an inner dimension in a clean room of class 10000 of 305 ⁇ 305 ⁇ 305 mm. The rubbing was carried out 10 times at a speed of 1 reciprocation / sec, and the number of foreign matters having a particle size of 0.5 ⁇ m or more in the cube was measured with a particle counter. 3) As a result, the dust generation amount of the interleaf paper before the cleaning process was 16,200. In contrast, the amount of dust generated after the cleaning process is 9,200. Therefore, the dust generation amount of the interleaving paper that has been cleaned is greatly reduced.
