Abstract
An inexpensive cleaning sheet is provided which attains an excellent cleaning efficiency and with which even large dust particles or heavy dust particles can be easily caught. The cleaning sheet is obtained by bonding a cleaning-side sheet to a base sheet at bonding areas, interposing a strip between the base sheet and the cleaning-side sheet, bonding the strip to the cleaning-side sheet, with one end of the strip projecting outward from the cleaning-side sheet, forming a perforation for cutting off in the cleaning-side sheet, and forming a pressure-sensitive adhesive layer on the surface of the base sheet which faces the region of the cleaning-side sheet surrounded by the perforation. This cleaning-side sheet is configured so that the region of the cleaning-side sheet surrounded by the perforation is cut off by pulling the strip.
