An infrared ray-reflecting film that includes a laminate obtained by alternately laminating two or more layers having different refractive indices on a light-transmitting substrate, in which: a difference in refractive index (e.g., for light having a wavelength of 589 nm) between any adjacent layers falls within a range of 0.1 to 0.4; and a detected peak is observed at a depth where an interfacial region between the respective layers exists in elemental analysis in a depth direction of the film by a glow discharge optical emission spectrometry. Further, a detected peak is observed at a depth where detected signals derived from components that construct adjacent layers contact each other in elemental analysis in a depth direction of the film by a glow discharge optical emission spectrometry.
