Claim:
1. An infrared ray shielding film having one or more metal particle-containing layers that contain at least one kind of metal particle, wherein: hexagonal and/or circular tabular metal particles are contained in 60% by number or more relative to a total number of the metal particles contained in the one or more metal particle-containing layers, and at least one of the one or more metal particle-containing layers has at least two absorption peaks or at least two reflection peaks in a region of 800 nm to 2000 nm, and further has a thickness of from 10 nm to 80 nm, wherein said thickness and a thickness of the hexagonal and/or circular tabular metal particles satisfy relationship 2a≦d≦8a, wherein a is the thickness of the hexagonal and/or circular tabular metal particles, and d is the thickness of the at least one of the one or more metal particle-containing layers, and wherein the RMS granularity of the tabular metal particles is 25 or less.
