To provide a rolling die that is able to cut an amorphous material while preventing wear.SOLUTION: A rolling die 30, which is a die for cutting an object O, comprises: an anvil roller 31, a die cutter 32, a first elastic portion 33, and a second elastic portion 34. The anvil roller 31 rotates while supporting the object O. The die cutter 32 has a projecting blade 32a for cutting the object O and rotates. A first elastic portion 33 is disposed on an outer peripheral surface of the anvil roller 31 and elastically deforms in contact with a rear surface of the object O during cutting of the object O. The second elastic portion 34 is disposed on an outer peripheral surface of the die cutter 32 and elastically deforms in contact with the surface of the object O during cutting of the object O. The hardness of the first elastic portion 33 is greater than the hardness of the second elastic portion 34.SELECTED DRAWING: Figure 2A 【課題】損耗を抑制しつつ非晶質材料を切断可能なロール金型を提供する。【解決手段】ロール金型３０は、対象物Ｏを切断する金型であって、アンビルローラ３１と、ダイカッター３２と、第１弾性部３３と、第２弾性部３４と、を備える。アンビルローラ３１は、対象物Ｏを支持して回転する。ダイカッター３２は、対象物Ｏを切断する凸刃３２ａを有して回転する。第１弾性部３３は、アンビルローラ３１の外周面に配置され、対象物Ｏの切断時に対象物Ｏの裏面に接して弾性変形する。第２弾性部３４は、ダイカッター３２の外周面に配置され、対象物Ｏの切断時に対象物Ｏの表面に接して弾性変形する。第１弾性部３３の硬さは、第２弾性部３４の硬さよりも硬い。【選択図】図２Ａ
