A method of manufacturing an Fe-based amorphous alloy ribbon includes forming a coated film of a molten alloy on a peripheral surface of a chill roll that has been subjected to polishing using a polishing brush roll, cooling the coated film on the peripheral surface, and then winding the Fe-based amorphous alloy ribbon, which has been peeled off by a peeling means, on a wind-up roll, to obtain a wound body of an Fe-based amorphous alloy ribbon.The polishing brush roll includes a roll axis member and a polishing brush that is equipped with a plurality of brush bristles and satisfies the following condition (1) and condition (2) while rotating axially in a reverse direction to the chill roll.• Condition (1): Free length of brush bristles is more than 30 mm but no more than 50 mm.• Condition (2): Density of brush bristles at the brush bristle tip is more than 0.30 bristles/mmsup2/supbut no more than 0.60 bristles/mmsup2/sup.
