<P>PROBLEM TO BE SOLVED: To provide a heat shielding film capable of shielding highly a heat ray ranging from a near-infrared ray to a far-infrared ray. <P>SOLUTION: The heat shielding film contains a titanium oxide particle having 0.5-5 μm of average particle size, total ray reflectivity is 55% or more in every wavelength of incident rays within a wavelength of 800-2,200 nm, and an average ray transmittance is less than 45% in each of incident rays within a wavelength range of 2,500-8,000 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
