<P>PROBLEM TO BE SOLVED: To provide an antireflective film which has a low refractive index layer excellent in low refractive index, scratch resistance, antifouling properties, and transfer properties. <P>SOLUTION: The antireflective film includes at least one low refractive index layer on a transparent substrate film, wherein the low refractive index layer is formed of a coating composition containing at least (A) a fluorine-containing antifouling agent having a weight average molecular weight Mw of less than 10,000, a polymerizable unsaturated group and a structure represented by formula (F) shown below, (B) a polyfunctional monomer having a polymerizable unsaturated group and (C) an inorganic fine particle, and a content of the fluorine-containing antifouling agent (A) is 1% by mass or more and less than 25% by mass based on a total solid content of the coating composition. The formula (F): (Rf)-[(W)-(R<SB>A</SB>)<SB>n</SB>]<SB>m</SB>wherein, Rf represents (per)fluoroalkyl group or (per)fluoropolyether group, W represents a connecting group, RA represents a functional group having a polymerizable unsaturated group, n represents an integer of from 1 to 3, and m represents an integer of from 1 to 3. <P>COPYRIGHT: (C)2011,JPO&INPIT
