When a passerby (passenger) steps on the dust mat 110, the sole of the shoe is pressed against the adhesive layer of the adhesive sheet 131, and dust such as dirt and dust adhering to the sole adheres to the adhesive sheet 131 and is removed from the shoe. To be removed. Therefore, the shoes of the person who entered the room are in a cleaned state, while the removed dust is held by the adhesive sheet 131.

In such a dust mat 110, as the amount of dust attached increases, the adhesive force of the adhesive sheet 131 decreases. Therefore, after a certain amount of use, when the uppermost adhesive sheet 131 is peeled off and the adhesive layer of the lower adhesive sheet 131 is exposed, the same adhesive strength as that of a new article can be obtained. The peeled adhesive sheet 131 will be discarded together with the attached dust.

In the dust mat 110 as described above, each adhesive sheet 131 is colored white so that the amount of dust adhered can be seen, and therefore the degree of dirt on the dust sheet 131 can be directly visually confirmed. ing.

However, even if the stain can be visually confirmed, whether or not the adhesive sheet 131 should be peeled off and discarded depends on the sense of the observer, and the peeling time is different.

It is uneconomical to peel off and dispose of even if the amount of dust adhered is small, but if the peeling time is missed, conversely,
The ability to remove dust is lost, and the adhesive sheet 131
If excess dust adheres to the adhesive sheet 131
There is a problem in that dust is peeled off from the top and becomes a pollution source and is brought into a clean room or the like.

Further, when printing the advertisement on the dust mat, since the adhesive sheets 131 are discarded one after another, it is necessary to print on all the adhesive sheets 131, resulting in a high cost.

Furthermore, the dust mat 11 as described above
In No. 0, a synthetic resin film such as a PET film is used for the release sheet 131.
When disposing 31, the harmful gas is generated when trying to incinerate, or there is a problem that it does not decompose even if it is landfilled and discarded.
