Abstract: An infrared-ray reflective film (100) of the present invention is configured by disposing an infrared reflective layer (20) and a transparent protective layer (30) on a transparent film backing (10) in this order. The infrared reflective layer (20) comprises: a first metal oxide layer (21); a metal layer (25) made of a silver alloy containing silver in an amount of 96 to 99.9 weight%; and a second metal oxide layer (22), which are arranged in this order from the side of the transparent film backing (10), wherein each of the first metal oxide layer (21) and the second metal oxide layer (22) is in direct contact with the metal layer (25). There is no metal layer between the transparent film backing (10) and the infrared reflective layer (20) and between the infrared reflective layer (20) and the transparent protective layer (30). Preferably, the infrared-ray reflective film of the present invention has a visible ray transmittance of 65% or more, a shading coefficient of less than 0.60, and a corrected emissivity as measured from the side of the transparent protective layer of 0.20 or less.
