Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a core which inhibits deformation etc. of a film wound therearound, has high reusability of a core body, enables combination of various materials, and achieves cost reduction.SOLUTION: A core 10 of the invention has: a cylindrical surface core 1; and a cylindrical center core 2 which has an outer diameter having the substantially same size with an inner diameter of the surface core 1 and is inserted into the surface core 1. The surface core 1 can be replaced by being detached from and attached to the center core 2.SELECTED DRAWING: Figure 1 【課題】巻き取るフィルムの変形等を抑制できると共に、コア本体の再利用性が高く、様々な材料の組合せが可能であって、低コスト化を図れるコアを提供する。【解決手段】本発明のコア１０は、円筒状の表面コア１と、外径が表面コア１の内径と略同一であって、表面コア１の内側に挿入された円筒状の芯コア２とを有し、前記表面コア１は前記芯コア２から着脱して交換可能であることを特徴とする。【選択図】図１
