The invention provides a temperature-sensitive narrow-band pass filter, which is characterized in that a vanadium dioxide thin film is constructed in the temperature-sensitive narrow-band pass filter as a microcavity layer for the first time. The temperature-sensitive narrow-band pass filter comprises a top layer ordered thin film system, a defective layer thin film and a bottom layer ordered thin film system, which are laminated in sequence from top to bottom, wherein the defective layer thin film is the vanadium dioxide thin film, and the laminated structures of the top layer ordered thin film system and the bottom layer ordered thin film system are vertically and symmetrically distributed by using the defective layer thin film as a symmetry axis. The film systems of the temperature-sensitive narrow-band pass filter can be used for aiming at one narrow bandwidth range; the interference of light rays in other wavebands can be avoided; and furthermore, the service time effectiveness of the filter is improved greatly. Compared with a conventional dielectric filter, the film systems of the temperature-sensitive narrow-band pass filter have the characteristic of being sensitive to the temperature. Through designing the thicknesses of the symmetrical film systems on two sides and the thickness of a defective layer, the thicknesses of the symmetrical film systems can be reduced, so as to reduce processing time in process.
