Provided are: an antifouling antireflection film that has improved antifouling properties while sustaining an antireflection performance of a porous silica film and can maintain a good appearance over a long period of time; an article equipped with the antifouling antireflection film; and a method for manufacturing the same. The antifouling antireflection film comprises a porous silica film and an antifouling layer coating the surface of the porous silica film, wherein the antifouling layer comprises a plurality of nanosheets, the nanosheets are formed of a low refraction material having a refractive index of 1.4-1.65, and the average film thickness of the antifouling layer is 0.4-40 nm.
