PROBLEM TO BE SOLVED: To provide a laminate film having infrared ray-reflecting property and visible light-transmitting performance at high levels, high durability even in long-term use, and particularly suitable for sticking to a window.SOLUTION: The laminate film includes one or more heat ray-reflecting layers, a metal oxide thin film (1), and a hard coat layer on at least one surface of a substrate, layered in this order from the substrate side. The heat ray-reflecting layers are composed of a metal oxide thin film (2), a metal thin film, and a metal oxide thin film (3), layered in this order from the substrate side. The metal oxide thin film (2) has an oxygen content lower than both of an oxygen content of the metal oxide thin film (1) and an oxygen content of the metal oxide thin film (2). |
