The infrared ray reflective film 100 is provided with a metal oxide layer 21, an infrared ray reflective layer 23 composed mainly of silver, and a light absorbing metal layer 25 in this order on a transparent film base 10, There is no metal layer between the film substrate 10 and the infrared reflecting layer 23. The transparent film base material 10 preferably has a cured resin layer 12 on the surface of the metal oxide layer 21. The metal oxide layer 21 is preferably composed of a composite metal oxide containing zinc oxide and tin oxide. The light absorbing metal layer 23 has a film thickness of 2 nm to 10 nm and contains at least one selected from the group consisting of nickel, chromium, niobium, tantalum, and titanium. |
