Abstract: Provided is an infrared reflective film in which a reflective layer and a protective layer are sequentially layered on one surface of a substrate. The protective layer contains a polymer, and the dynamic friction coefficient on the surface of the protective layer is 0.001 to 0.45.

Abstract: A radiant heat conduction-suppressing sheet according to an embodiment of the present invention includes: a heat conduction-suppressing layer and a heat conductive layer. The heat conduction-suppressing layer has a heat conductivity of 0.06 W/m·K or less. The heat conductive layer has a far-infrared absorptivity at a wavelength of 7 ?m to 10 ?m of 0.6 or less, and a heat conductivity of 200 W/m·K or more. The radiant heat conduction-suppressing sheet is used by being fixed to a housing containing a heating element under a state in which a side of the heat conduction-suppressing layer is fixed to the housing at such a position that the heat conductive layer faces a heat radiating surface of the heating element while being free of close contact with the heating element.
