To provide a method for manufacturing amorphous alloy pieces by punching from an amorphous alloy ribbon, capable of improving a tool life by an another method which does not depend on tool coating only.SOLUTION: An objective method for manufacturing amorphous alloy pieces is characterized by forming a plasticity processing groove which becomes a punching border line of a prescribed shape on the surface of an amorphous alloy ribbon by a tool for stamp, and by punching along the plasticity processing groove using a punch for punching and a die to obtain the amorphous alloy piece.SELECTED DRAWING: Figure 2 【課題】非晶質合金リボンから非晶質合金片を打抜き加工する、非晶質合金片の製造方法において、工具コーティングだけに依存しない別の方法で、工具寿命を改善することが可能な、製造方法を提供する。【解決手段】非晶質合金リボンの表面に、刻印用工具により、所定形状の打抜き輪郭線となる塑性加工溝を形成し、打抜き用パンチ及びダイにより、前記塑性加工溝に沿って打抜き加工を行い、非晶質合金片を得る、ことを特徴とする非晶質合金片の製造方法。【選択図】 図２
