Abstract

The invention relates to provide an infrared shielding composition that can form an infrared cut filter in which flat coating properties are excellent and the generation of a pattern on the surface is suppressed and that has excellent drying resistance, an infrared cut filter, and a solid-state imaging device. The infrared shielding composition according to the invention includes at least metal containing tungsten oxide particles; a resin binder; a solvent A of which a boiling point is 170° C. to 200° C. at 1 atm; and a solvent B different from the solvent A, in which a content of the solvent A is 0.1 to 20 mass % with respect to a total mass of the infrared shielding composition.
