<p>Disclosed is a method for manufacturing a near infrared reflective body in which a near infrared reflective film is manufactured that has excellent manufacturing cost performance, is capable of being employed over a large area, has excellent application stability, and has excellent resistance to refractive index irregularity in the surface. A method for manufacturing a near infrared reflective film in which a high refractive index layer and a low refractive Index layer are alternately laminated on a support body, wherein the difference in the refractive index of adjacent high refractive index layers and low refractive index layers is at least 0.3, and the near infrared reflective film is formed using a high refractive index layer application fluid and a low refractive index layer application fluid such that, if the viscosity of the high refractive index layers and low refractive index layers at 15 °C is ·15 and the viscosity at 45 °C is ·45, the viscosity ratio (·15/·45) in each case is at least 2.0.</p> |
