Abstract: The present invention provides a thermochromic film in which vanadium dioxide can be used without a doping process after the phase transition temperature thereof is reduced, and thus, there are economic and environmental advantages, and a method for manufacturing a thermochromic film, the method comprising: a formation step of forming a coating layer by applying a solution including untreated vanadium oxide onto a substrate; and a formation step of forming a thermochromic layer by phase change of untreated vanadium oxide to vanadium dioxide through annealing using intense pulsed light (IPL).
