An objective of the present invention is to provide an antireflection film
having a fine particle layer that is formed on a transparent substrate
without allowing particles to aggregate as irregular lumps, while the
region having no particles is being reduced to an area that is
sufficiently small so as not to impair the visibility. In order to
achieve the above-mentioned objective, the present invention provides an
antireflection film that is characterized by having: a transparent
substrate and a fine particle layer that is placed on the surface of the
transparent substrate and made from at least a single layer of fine
particles, wherein the surface of the transparent substrate and fine
particles are allowed to adhere to each other by at least an
electrostatic interaction, while the bulk of the above-mentioned fine
particle layer is set to have a refractive index lower than the
refractive index of the above-mentioned transparent substrate.
