To provide a cleaning sheet capable of satisfying both the strength for cleaning and the degree of freedom of fiber needed for dust collecting performance, and more concretely, capable of collecting dust ranging from large one such as cotton-like dust, thread wastes, hairs, etc., to minute dust such as earth dust.

The cleaning sheet 1 is integrated with a net-like sheet 2 on one or both surfaces of which is formed a non-woven cloth-like fiber aggregate 3 in an entangled state among the composing fibers as well as with the net-like sheet, the entangling coefficient in the fiber aggregate as expressed by the initial gradient of stress-strain curve vertical to the fiber arrangement direction being 10-500m.
