PROBLEM TO BE SOLVED: To provide a method for producing an amorphous alloy thin strip and a production device therefor where, when an amorphous alloy thin strip is produced using a cooling roll, during the production, the circumferential face of the cooling roll is ground in the width direction of the cooling roll online, a sound state is maintained for a long time, and an amorphous alloy thin strip having excellent magnetic properties is mass-produced. SOLUTION: In the method for producing an amorphous alloy thin strip by jetting a molten alloy on the circumferential face of a cooling roll during high speed rotation and rapidly cooling and solidifying the same, during the production of the thin strip, when the circumferential face of the cooling roll after the separation of the amorphous alloy thin strip is ground to the width direction of the cooling roll, it is ground in such a manner that (i) at least two grinding means having different grinding properties are arranged to the rotational direction of the cooling roll and (ii) the grinding means are brought into contact with the circumferential face of the cooling roll at a length of≥0.2% of the circumference of the cooling roll, so as to perform the grinding.
