Abstract
The infrared reflective device includes infrared reflective members which reflect infrared rays. The infrared reflective members include colloidal particles arranged at regular spacing, and a filler material intervening in the spaces between the colloidal particles. The difference between the refractive index of the colloidal particles and the refractive index of the filler material is set so as to be 0.05 or less in the visible light region and 0.1 or above in the infrared region, whereby visible light is transmitted while infrared rays are reflected.
