摘要： In a heat-shielding film formed of addition-curing silicone resin containing organopolysiloxane, organopolysiloxane includes the combination of a plurality of units including at least a R1SiO3/2 unit (a T unit), a R2R3SiO2/2 unit (a D unit), and a R4R5R6SiO1/2 unit (a M unit) (in each unit, R1 to R6 is aliphatic hydrocarbon or hydrogen), and the molar ratio of the T unit, the D unit, and the M unit among all structural units is T:33.3 mol % to 71.4 mol %, D:11.1 mol % to 42.9 mol %, and M:7.0 mol % to 42.9 mol %.

摘要： A heat insulating layer contains many hollow particles, a silicone-based resin binder, and silica nanoparticle. The percentage of the silica nanoparticles in the total amount of the resin binder and the silica nanoparticles is equal to or greater than 10% by volume and equal to or smaller than 55% by volume.
