Summary:To provide a super-water repellent film having high transparency, super-water repellency and antistaticity.SOLUTION: The super-water repellent film comprises: a polymer layer having an uneven structure having a plurality of projections provided at a pitch equal to or less than the wavelength of visible light on a surface; and transparent conductive particles arranged in depressions provided between the plurality of projections. The polymer layer is the cured product of a polymerizable composition including a polyfunctional acrylate, a monofunctional acrylate and a fluorine containing release agent having a perfluoro polyether group; the transparent conductive particles are arranged at positions deeper than the tips of the plurality of projections in the depressions; and the tips are exposed to the outermost surface of the super-water repellent film.SELECTED DRAWING: Figure 1 【課題】高い透明性、超撥水性及び帯電防止性を兼ね備えた超撥水性フィルムを提供する。【解決手段】複数の凸部が可視光の波長以下のピッチで設けられた凹凸構造を表面に有する重合体層と、上記複数の凸部間に設けられた凹部内に配置された透明導電性粒子と、を備える超撥水性フィルムであって、上記重合体層は、多官能アクリレートと、単官能アクリレートと、パーフルオロポリエーテル基を有するフッ素含有離型剤とを含有する重合性組成物の硬化物であり、上記透明導電性粒子は、上記凹部内の上記複数の凸部の先端よりも深い位置に配置され、上記先端が上記超撥水性フィルムの最表面に露出している超撥水性フィルム。【選択図】 図１
