To provide a fluid resistance reduction film capable of being applied to a surface of an object to effectively reduce fluid resistance, a roll body, and a method for manufacturing a fluid resistance reduction film.SOLUTION: A fluid resistance reduction film of the present disclosure is a fluid resistance reduction film having a fluid resistance reduction structure capable of reducing fluid resistance, and has, on a first surface, first regions having an uneven structure composed of convex parts and concave parts and second regions adjacent to the first region. The first regions and the second regions are alternately arranged in a first direction on the first surface. The first regions and the second regions extend in a band shape in a direction intersecting the first direction. The extent of elongation in the first direction on the first surface is smaller than the extent of elongation in the direction in which the first regions and the second regions extend in a band shape.SELECTED DRAWING: Figure 1 【課題】 物体の表面に適用されて効果的に流体抵抗を低減することが可能な流体抵抗低減フィルム、ロール体、および流体抵抗低減フィルムの製造方法を提供する。【解決手段】 本開示の流体抵抗低減フィルムは、流体抵抗を低減可能な流体抵抗低減構造を有する流体抵抗低減フィルムであって、第１面に、凸部と凹部から構成される凹凸構造を有する第１領域と前記第１領域に隣接する第２領域とを有し、前記第１面における第１方向において、前記第１領域と前記第２領域とが交互に配置されており、前記第１領域および前記第２領域は、前記第１方向に交差する方向に帯状に延びており、前記第１面における第１方向の伸びの大きさが、前記第１領域および前記第２領域が帯状に延びる方向の伸びの大きさよりも小さい。【選択図】 図１
