摘要

PROBLEM TO BE SOLVED: To provide a cleaning sheet having a structure body further removing and containing various types of dirt.

SOLUTION: A cleaning sheet 10 includes one or more high basis weight regions 12 having a basis weight of about 30 to about 120 g/cm2, and one or more low basis weight regions 14 having a low basis weight being not more than about 80% of the basis weight of the high basis weight regions. In addition to having multiple basis weights, the macroscopically three-dimensional cleaning sheet can include a scrim material which contracts so as to provide a macroscopic three-dimensional structure when heated and then cooled.
