Abstract
The present invention provides an infrared ray blocking transparent film which can be produced at low cost despite using indium tin oxide powder (which can inhibit metallic luster) and which can exhibit excellent electromagnetic wave transmissivity. An infrared ray blocking layer is provided on at least a surface of a base film, and the infrared ray blocking layer includes indium tin oxide powder and resin in a weight ratio of 90/10 to 60/40.
