Abstract
A near-infrared ray shielding film which has high adhesion between layers, is substantially transparent, can shield a wide near-infrared region at a high level and is free from electromagnetic interference. This near-infrared ray shielding film is a multi-layer laminated film consisting of a first laminated film portion and a second laminated film portion, each consisting of first layers and second layers alternated with each other, and the average thickness of all the layers of the second laminated film portion is 1.05 to 1.6 times the average thickness of all the layers of the first laminated film portion.
