Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a separator wound body, and the like, capable of suppressing meandering thereof.SOLUTION: A separator wound body (10) is obtained by winding a separator (12) for a battery about a core (8). In the core (8), a shaft hole (H) is provided along the central axis (CA) thereof. The value obtained by dividing a difference between the diameter of the core (8) and the diameter of the shaft hole (H) by the width of the core (8) in a central axis (CA) direction is 0.3 or more and 1.5 or less.SELECTED DRAWING: Figure 6 【課題】蛇行を抑制できるセパレータ捲回体等を提供する。【解決手段】セパレータ捲回体（１０）は、コア（８）に電池用のセパレータ（１２）を捲回したものである。コア（８）には、その中心軸（ＣＡ）にそって軸穴（Ｈ）が設けられている。コア（８）の直径と軸穴（Ｈ）の直径との差を、コア（８）の中心軸（ＣＡ）方向の幅で除算した値は、０．３以上１．５以下である。【選択図】図６
