PROBLEM TO BE SOLVED: To provide a laminate film having a hard coat layer which has high durability and excellent infrared reflection performance, transparency and scratch resistance and is suitable for pasting on a window.SOLUTION: There is provided a laminate film formed by laminating a heat ray reflecting layer and a hard coat layer in this order on one surface of a substrate composed of a synthetic resin, where the heat ray reflecting layer has a multi-layer structure in which a metal thin film and a metal oxide thin film are alternately laminated (when the number of the layers of the metal thin film is defined as "n", the number of the layers of the metal oxide thin film is "n+1"), the metal oxide thin film in contact with at least the hard coat layer contains tin as the main component of the metal component and contains 3 to 20 mass% of niobium of the metals. |
