Abstract: The present invention has the objective of providing an infrared reflective film by means of which it is possible to achieve an effective heat-shielding performance with a smaller number of layers than hitherto using a construction employing specified infrared reflective layers. Solution Means The infrared reflective film of the present invention has at least two infrared reflective layers and, of these infrared reflective layers, the center reflective wavelength of at least one infrared reflective layer is between 1200 and 1300 nm. Furthermore, the laminated glass of the present invention is formed by interposing this infrared reflective film between two sheets of intermediate film, and laminating these between two sheets of glass.
