Abstract: Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.

Abstract: The stretchable porous film of the present invention includes voids in a surface thereof, in which: the stretchable porous film has an air permeability measured with an Oken-type air permeability meter of less than 99,999 sec/100 cc; the stretchable porous film has such an extending direction that an air permeability measured with the Oken-type air permeability meter in a state in which the stretchable porous film is extended by 100% becomes less than 60,000 sec/100 cc; and the stretchable porous film has such a pulling direction that when, in a hysteresis test, the stretchable porous film is pulled from a width of 20 mm and an inter-chuck distance of 30 mm to an inter-chuck distance of 60 mm at a pulling speed of 50 mm/min and held for 1 minute, and then the pulling of the inter-chuck distance is released, a residual strain becomes 10 mm or less.
