A sealing member for preventing escape of micro particles, sealing a predetermined gap between a movable unit in contact with the micro particles and a housing of the movable unit, and adhered to the face of the movable unit or housing without impeding movement of the movable unit, based on a pile fabric configured with a pile yarn forming a sliding flock and a base cloth of plain woven tissue supporting the pile yarn, the pile yarn of the flock being formed of a high strength polyethylene fiber having a filament fineness of 0.1-6.0 dTex, a fiber cross section oblateness of at least 1.1, and an average tensile strength of at least 22 cN/dTex, and the flock having a height of 1.5-4.0 mm, a pile density of 13,000-346,000 filament/cm<2 >at the pile yarn portion, and a pile yarn cross section area of 0.02-0.2 cm<2>per 1 cm<2 >of the base cloth. The sealing member includes a coating layer at the back side of the base cloth to prevent fall off of the flock, and is superior in sidability and abrasion resistance.
