The infrared reflector of the present invention has an infrared-reflecting layer and an infrared-permeable layer which is formed on the infrared-reflecting layer. The infrared-reflecting layer has a reflectance of 60% or more and a permeability of 25% or less with respect to infrared rays having a wavelength within a range of 800 to 1600 nanometers. The infrared-permeable layer has a reflectance of less than 60% and an absorbance of 50% or less with respect to infrared rays having a wavelength within a range of 800 to 1600 nanometers. The infrared-permeable layer contains resin components and pigments, and the amount of carbon black contained in the infrared-permeable layer is 0.1 wt % or less. This infrared reflector can provide various coloration that includes dark colors while maintaining the high infrared reflectivity on the whole.
