The infrared ray reflective substrate 100 includes an infrared ray reflective layer 23 mainly composed of silver and a light absorbing metal layer 25 in this order on a transparent film substrate 10. The thickness of the light absorbing metal layer 25 is 15 nm or less and the thickness of the transparent protective layer 30 is 10 nm to 120 nm. The distance between the light absorbing metal layer 25 and the transparent protective layer 30 is 25 nm or less. INDUSTRIAL APPLICABILITY According to the present invention, there is provided an infrared reflective substrate having low visible light reflectivity, excellent in visibility, and excellent in productivity. |
