A detecting device includes a wavelength dispersion element for dispersing light into wavelengths and for emitting dispersed light, a photodetector for detecting the dispersed light, and a wavelength restriction element, which is arranged between the wavelength dispersion element and the photodetector and has an optical characteristic dependent on a wavelength, for restricting an incidence of light having a particular wavelength to the photodetector. Light that is part of the dispersed light and includes the light having has the particular wavelength is incident to the wavelength restriction element.
