Infrared shielding sheet, method for manufacturing the same, and use of the same

An infrared shielding sheet comprising a laminated film formed by alternately laminating at least one high refractive index resin layer containing fine particles and at least one low refractive index resin layer containing fine particles,

• wherein at least one of the at least one low refractive index resin layer contains the fine particles in an amount of from 40 to 95 wt. %, and has a value of 0.1 or more that is obtained by subtracting a refractive index at an arbitrary wavelength from 780 to 2500 nm from a refractive index at a wavelength of 550 nm, and
• the at least one low refractive index resin layer has a refractive index lower than a refractive index of the at least one high refractive index resin layer at any wavelength in a range from 550 nm to the arbitrary wavelength inclusive.
