PROBLEM TO BE SOLVED: To provide a storage box of a winding body which is excellent in drawing performance of a rap film and can inhibit costs.SOLUTION: A storage box of a winding body comprises a body part which stores a rap roll around which a rap film is wound, and a lid part which has a cutting blade that cuts the rap film. The body part has an opening portion, a bottom face plate, a front face plate, a back face plate, and a pair of side face plates. The front face plate comprises a front plate end edge which is an end edge that intersects with the opening portion. At least one portion of the front plate end edge is in sliding contact with a drawn rap film. Arithmetical average height Sa of at least one portion which is in sliding contact with the rap film, in the front plate end edge, is 2.8 μm or more and 6.0 μm or less, and a coefficient of dynamic friction between the rap film and the front plate end edge, in a case the rap film is drawn via the front plate end edge, is 0.3 or less.SELECTED DRAWING: Figure 1 【課題】ラップフィルムの引出性がよく、かつコストも抑制できる巻回体収容箱を提供する。【解決手段】ラップフィルムが巻回されたラップロールを収納する本体部と、前記ラップフィルムを切断する切断刃を有する蓋部とを備える巻回体収容箱であって、前記本体部は、開口部、底面板、前面板、後面板、および一対の側面板を有し、前記前面板は、前記開口部と交わる端辺である前板端辺を備え、前記前板端辺の少なくとも一部は、引き出される前記ラップフィルムと摺接し、前記前板端辺の少なくとも前記ラップフィルムと摺接する部分の算術平均高さＳａが２．８μｍ以上６．０μｍ以下であり、かつ前記ラップフィルムが前記前板端辺を介して引き出されるときにおける前記ラップフィルムと前記前板端辺との動摩擦係数が０．３以下である。【選択図】図１
