PROBLEM TO BE SOLVED: To provide an antireflection film with excellent antireflection performance at low cost, and to provide a reflection film with excellent scratch resistance having a reflective index of 1.0% or lower.SOLUTION: An antireflection film has a transparent base material, a hard coat layer, and a low refractive index layer. A coating material used for forming the low refractive index layer includes a compound having a perfluoroalkyl chain or a perfluoropolyether chain, and two ethylenic double bonds. A refractive index of the compound is 1.36-1.39, and a content of the compound is 5-30 wt% with regard to a solid content of the coating material. |
