Provided are a heat insulation film, a method for manufacturing the heat insulation film, a heat insulation glass, and a window which can realize a low manufacturing cost and achieve both low haze and high heat insulation. The heat insulation film comprises a supporting body, a fibrous conductive particle-containing layer, and a protective layer in that order, wherein the fibrous conductive particle-containing layer includes a binder and the fibrous conductive particles, the main component of the binder being a material of which the maximum peak reflectance value of far infrared radiation with a wavelength of 5-25 μm is at least 20%, or being a material of which the average transmittance of far infrared radiation with a wavelength of 5-10 μm is at least 50% when expressed in terms of a film thickness of 20 μm; and the protective layer includes, as the main component, a material of which the average transmittance of far infrared radiation with a wavelength of 5-10 μm is at least 50% when expressed in terms of a film thickness of 20 μm. |
