PROBLEM TO BE SOLVED: To obtain a method in which a change in a signal of a surface plasmon is signal-processed as a change in a synchrotron radiation and to obtain a signal processing element by using the method. SOLUTION: In the method for processing the signal by the surface plasmon, a dielectric layer 2 is arranged on a metal thin film 1, an optical coupler composed of a light transmission medium 3 is arranged on its opposite side, a single or multiple surface plasmon is excited in an interface between the dielectric layer 2 and the metal thin film 1 by using an excitation light source 4 and an excitation light source 5, the signal of the surface plasmon is changed due to a change in the dielectric layer 2, and the signal is processed by using the change in the synchrotron radiation due to the resonance of the changed surface plasmon with the optical coupler.
