Zusammenfassung:	To provide a core that can inhibit a lower core from falling and being damaged when taking a stacked upper core where those cores (separator winding core) adhere to each other after washing them and storing those wet cores while stacking them.SOLUTION: A core (u1, u2) formed by winding a separator for a non-aqueous electrolyte secondary battery includes a recess part (20) at a side face of the core (u1, u2).SELECTED DRAWING: Figure 5 【課題】洗浄した後に、濡れたコア（セパレータ巻芯）を重ねて保管する際に、コア同士がくっ付いてしまい、重ねられた上のコアを取る際に下のコアが落下し損傷が生じるのを抑制することができるコアを提供する。【解決手段】非水電解液二次電池用セパレータが捲回されるコア（ｕ１・ｕ２）であって、コア（ｕ１・ｕ２）の側面は、凹部（２０）を有する。【選択図】図５
