PROBLEM TO BE SOLVED: To provide a cleaner material which can easily and cleanly erase characters and images drawn on a board without being greatly deformed even when receiving force which is applied when performing wiping operation and which, when the surface layer is soiled, can peel it, and uses a layer underneath to cleanly erase again, in a board which frequently repeats drawing and erasing like a white board. SOLUTION: The cleaner material is a non-woven fabric structure in which two or more layers of non-woven fabric layers including wet-heat adhesive fibers are laminated by adhesion of the wet-heat adhesive fibers, and in which the laminated body has the non-woven fabric layers with the thickness of 0.2-2 mm, wherein each layer is peelable, and the inter-layer peeling strength lies within a range of 0.2-20 N/5 cm. The method for manufacturing of the cleaner material is also provided including a process in which the wet-heat adhesive fibers are adhered using high temperature water vapor.
