PURPOSE:To accurately produce an antireflection film even by lamination due to a coating method by forming a laminate by laminating the uppermost layer on a support base material so as to make the refractive index thereof min. and reducing the thickness of the laminate by a mechanical means to reduce the reflectivity at the interface of the laminate. CONSTITUTION:The resin layer 2 (high refractive index layer) formed on a support base material 1 has a refractive index relatively higher than that of the other resin layer 3 (low refractive index layer) to which the resin layer 2 is provided in a direct contact state but lower than that of the support base material 1. The resin layer 3 formed on the resin layer 2 has a refractive index relatively lower than that of the resin layer 2. The laminate thus obtained is deformed by a mechanical means such as an orientating method or a press method to be reduced in thickness. By this constitution, the reflectivity at the interface of air and the laminate is reduced. The supporting base material 1 is pref. relatively thicker than each of the resin layers 2, 3 formed thereon. |
