Abstract

The present disclosure relates to a die assembly used for notching or cutting an electrode plate of a secondary battery and a method of manufacturing the die assembly. The present disclosure provides a method of manufacturing a punch holder and a die holder of a die assembly for notching an electrode plate of a secondary battery, which includes fixedly overlapping a punch holder and a die holder, simultaneously polishing side surfaces of the punch holder and the die holder overlapping each other, setting a center point of each of the punch holder and the die holder overlapping each other, and generating a reference hole passing through each of the punch holder and the die holder overlapping each other at a position spaced from the center point, and a notching die assembly manufactured by the method.
