PROBLEM TO BE SOLVED: To provide a cellulose nonwoven fabric lint-free wiper which hardly pollutes the environment with fine particles. SOLUTION: This lint-free wiper is a flat sheet consisting of at least two layered nonwoven fabrics, and the layered nonwoven fabrics are made of cellulose. Between the layered fabrics, there are dot-like parts integrally pressed while remaining the interface of fibers substantially. The area of the dot-like parts integrally pressed is 20-40% of the projected area of the flat sheet, and the dispersion density of the dot-like parts is 0.5-80 points/cm2.
