Abstract
An infrared shielding film is an infrared shielding film including: an organic binder; and a plurality of tin-doped indium oxide particles (ITO particles) dispersed in the organic binder, in which the average center-to-center distance between adjacent particles of the ITO particles is in a range of 9 nm or more and 36 nm or less, the ratio of the average center-to-center distance between the adjacent particles to the average primary particle diameter of the ITO particles is in a range of 1.05 or more and 1.20 or less, and a roughness Ra of a film surface is in a range of 4 nm or more and 50 nm or less.
