There is provided a new infrared-shielding sheet that has been improved to a large extent in terms of transparency in the visible light region, radio-wave transparency, infrared shielding properties, production cost, and hue. The infrared-shielding sheet includes: a laminated film having high-refractive index resin layers containing fine particles and low-refractive index resin layers containing fine particles alternately laminated therein; and an infrared-absorbent pigment layer containing an infrared-absorbent pigment having a visible light transmittance of 70% or greater and a b* value in the L*a*b* color system of 10 or less, wherein for at least one layer of the low-refractive index resin layers, a value obtained by subtracting the refractive index at an arbitrary wavelength in the range of 780 nm to 2,500 nm from the refractive index at a wavelength of 550 nm is 0.1 or greater, and the low-refractive index resin layers exhibit a lower refractive index than the high-refractive index resin layers at any arbitrary wavelength longer than or equal to 550 nm and shorter than or equal to the arbitrary wavelength.
