[0013]
The width W of the pressure-sensitive adhesive sheet 2 is not particularly limited, but is 20 to 600 mm, preferably 50 to 600 mm in consideration of the form of a cleaning tool to be worn, a floor, a surface to be cleaned such as clothing (including clothing), and the like. And particularly preferably 100 to 400 mm.
[0014]
In the present embodiment, the interval between the pair of cutting lines 22 is the width d of the peeling portion 23, and therefore, it is necessary that the width be easy to pick. The interval, that is, the width d of the peeling portion 23 is preferably 0.3 to 5 mm, particularly preferably 0.5 to 5 mm.
[0015]
There is no particular limitation on the form of the cutting line 22, but it is preferable that the cutting line 22 does not break during processing and breaks easily when a new surface is exposed. Specifically, it is preferable to adopt a form such as a broken line.
