PURPOSE:To obtain a high grade sheet like abrasive material with high quality by adhering micro-fiber crystal selected from a specific group on a sheet like base material and forming a polishing surface with the use of the top thereof. CONSTITUTION:Micro-fiber crystal, which is selected from a group of silicon carbide, silicon nitride, potassium titanate, aluminum oxide and zirconium oxide, is adhered on a sheet like base material. The micro-fiber crystal is formed with the top of the micro-fiber crystal. The micro-fiber like crystal is manufactured by an electro-static planting method, wherein static electricity is electrified on the base material on which the micro-fiber crystal is scattered and adhered. In this case, the micro-fiber like crystal is oriented in the piled state with the one top side downward by the polarity thereof as so to be adhered on the based material while holding the piled state.
