PPROBLEM TO BE SOLVED: To achieve an unprecedented new optical switching element in which an anomalous phenomenon caused by a diffraction grating and a wavelength of light is utilized in theory. PSOLUTION: The optical switching element 1 has: a resonant reflecting element 11 whose the thickness portion functions as a waveguide layer, the one surface of the thickness direction functions as a total reflection plane, and the other surface thereof has a fine periodic structure with fine unevenness formed thereon, wherein a predetermined wavelength component of light incident from the other surface is resonant reflected; and driving means 12, 14 for varying a resonant wavelength of the resonant reflection by varying a shape and/or a refractive index of the resonant reflecting element 11.
