This infrared radiation reflecting film (100) is provided with, in order, an infrared radiation reflecting layer (20) and a transparent protective layer (30) on a transparent film substrate (10). The infrared radiation reflecting layer (20) is provided with, in order from the transparent film substrate (10) side, a first metal oxide layer (21), a metal layer (25) composed mainly of silver, and a second metal oxide layer (22) comprising a composite metal oxide containing zinc oxide and tin oxide. The transparent protective layer (30) is in direct contact with the second metal oxide layer (22). The thickness of the transparent protective layer (30) is 30 nm to 150 nm, and is preferably an organic layer having a crosslinked structure derived from an ester compound having an acidic group and a polymerizable functional group in the same molecule. The content of the structure derived from the ester compound in the transparent protective layer (30) is preferably 1 wt% to 40 wt%. |
