Abstract

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 RSiOunit (a T unit), a RRSiOunit (a D unit), and a RRRSiOunit (a M unit) (in each unit, Rto Ris 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 %.
