PROBLEM TO BE SOLVED: To provide an infrared reflection substrate having a low reflectance for visible light, excellent visibility and excellent productivity.SOLUTION: An infrared reflection substrate 101 includes an infrared reflection layer 23 essentially comprising silver, a light-absorbing metal layer 25, and a transparent protective layer 30, in this order on a transparent film substrate 10. The light-absorbing metal layer 25 has a film thickness of 15 nm or less, and the transparent protective layer 30 has a film thickness of 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.SELECTED DRAWING: Figure 1 |
