Zusammenfassung:	Provided is a core (u1, u2) around which a nonaqueous electrolyte secondary battery separator is to be wound, and a side surface of the core (u1, u2) has a depression (20), wherein in a case where cores (separator winding cores) are stored by being stacked while still wet after cleaning, to prevent damage to a core caused by a problem where cores stick together and a lower core in a stack falls when a higher core in the stack is removed. 세정한 후에, 젖은 코어(세퍼레이터 권취 코어)를 겹쳐 보관할 때, 코어끼리 달라붙어 버려서, 겹쳐진 위의 코어를 취할 때 밑의 코어가 낙하하여 손상이 생기는 것을 억제할 수 있는 코어를 제공한다. 비수 전해액 이차 전지용 세퍼레이터가 권회되는 코어(u1, u2)이며, 코어(u1, u2)의 측면은 오목부(20)를 갖는다.
