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.

A pressure-sensitive adhesive tape comprising a substrate having thereon at least two different kinds of pressure-sensitive adhesive layers, wherein one pressure-sensitive adhesive layer (A) is constituted by a pressure-sensitive adhesive having a modulus at 50% elongation of 68,650 to 117,680 Pa and a modulus at 200% elongation of 147,100 to 245,170 Pa and another pressure-sensitive adhesive layer (B) is constituted by a pressure-sensitive adhesive having a modulus at 50% elongation of 19,610 to 68,650 Pa and a modulus at 200% elongation of 68,650 to 147,100 Pa. The pressure-sensitive adhesive tape has strong adhesion and suitable releasable properties. Use of such a tape in disposable diapers suppresses generation of discordant peeling sounds.
