Abstract

There is provided a method for manufacturing an alloy ribbon that suppresses different magnetic properties at each position of the alloy ribbon obtained by crystallizing an amorphous alloy ribbon. The method for manufacturing an alloy ribbon includes: heating a laminated body in which positions of thick portions of a plurality of amorphous alloy ribbons are shifted to a first temperature range less than a crystallization starting temperature; and heating an end portion in a lamination direction of the laminated body to a second temperature range equal to or more than the crystallization starting temperature after the heating the laminated body. An ambient temperature is held after heating the laminated body such that the laminated body is maintained within a temperature range in which the laminated body can be crystallized by heating the end portion to the second temperature range.
