The invention provides a durable abrasive article which can fit even to a surface of complicated shape and has excellent abrasive power and which does not give any deep scratch becoming a problem in a subsequent step and is not broken even when used in polishing a surface of complicated shape. An abrasive article comprising a flexible resin film, an abrasive grain layer formed on the surface of the resin film, and an extremely flexible resin layer formed on the abrasive grain layer, wherein the flexible resin film has a thickness of 10 to 200µm, a tensile strength of 30 to 130MPa and an elongation of 3 to 250%; the abrasive grains of the abrasive grain layer are of P280 to P12; and the extremely flexible resin layer has a 100% M of 1 to 20MPa, a tensile strength of 20 to 90MPa and an elongation of 250 to 1000%. |
