Abstract:
Provided is a transparent resin composition having a higher heat ray-shielding effect that can particularly effectively shield light of a wavelength of 1,450 nm to 1,750 nm while ensuring a high visible light transmittance. The transparent resin composition contains a transparent resin-forming component and inorganic particles, in which the inorganic particles contain indium tin oxide (ITO) and have a color having an L* value of 30 or more and 55 or less and a b* value of −18 or more and −10 or less in the Lab color space.
