The present disclosure provides a method that ensures easily manufacturing an alloy ribbon piece having excellent soft magnetic properties. The method is a method for manufacturing an alloy ribbon piece obtained by crystallizing an amorphous alloy ribbon piece and including: increasing a temperature of the amorphous alloy ribbon piece to a crystallization starting temperature; and increasing the temperature of the amorphous alloy ribbon piece from the crystallization starting temperature to a crystallization process termination temperature equal to or less than a crystallization completion temperature. A temperature increase rate of the amorphous alloy ribbon piece in the increasing of the temperature of the amorphous alloy ribbon piece from the crystallization starting temperature to the crystallization process termination temperature satisfies Q.sub.selfQ.sub.out+mcT where a self-heating amount, a heat discharge amount, a mass, a specific heat, and a temperature increase width of the amorphous alloy ribbon piece per unit time is Q.sub.self, Q.sub.out, m, c, and T, respectively.

One embodiment of the present invention provides an Fe-based amorphous alloy ribbon for an Fe-based nanocrystalline alloy, the Fe-based amorphous alloy ribbon being a cooled body of a molten metal that has been applied to a surface of a chill roll, wherein the Fe-based amorphous alloy ribbon includes a recess having a depth of 1 m or more in a 0.647 mm0.647 mm region located in a central part, in the ribbon width direction, of a ribbon surface, which is a cooled surface, in which a maximum area of the recess having a depth of 1 m or more is 3000 m.sup.2 or less; and a method of manufacturing the same.
