Abstract:
Provided is an abrasive film not likely to cause an end face defect of an optical fiber connector due to variation in load conditions during polishing, while providing a great grinding force. The abrasive film comprises a substrate film and an abrasive layer overlaid thereon, the abrasive layer comprising abrasive particles and a binder therefor and a wear quantity of the abrasive layer being from 10 mg to 25 mg. A content of the abrasive particles in the abrasive layer is preferably no less than 85% by mass. The abrasive particles preferably comprise first abrasive particles (primary particle diameter: of no less than 10 nm and less than 50 nm), and second abrasive particles (primary particle diameter: no less than 50 nm and less than 250 nm). An average thickness of the abrasive layer is preferably from 4 μm to 15 μm. The abrasive particles are preferably silica particles.
