The invention provides a plasmon narrowband absorption film comprising a substrate layer, a dielectric layer arranged on the surface of the substrate layer, an isolation layer arranged on the surface of the dielectric layer, and a dielectric particle layer arranged on the surface of the isolation layer. The dielectric particle layer is formed by a plurality of dielectric particles arranged according to a certain period. The film has the following advantages: firstly, compared with plasmon resonance of free electrons in metal particles, the film enables the thermal loss to be reduced substantially; secondly, electromagnetic resonance narrow-wavelength light absorption in a strong local area is realized and thus the action strength of the electromagnetic wave and the dielectric particles can be enhanced further, so that narrow-wavelength resonance response in a strong local area can be realized in a non-conformity environment; and thirdly, the absorption proportion of the electromagnetic energy in the dielectric layer and the dielectric particles can be adjusted, thereby reducing the metallic thermal losses.
