Abstract
There is provided a diffractive element including a first member, which includes a first resinand has a predetermined refractive index, and a second member, which has the same refractive index as the first memberhaving the predetermined refractive index in one wavelength of light and has a refractive index different from the first memberhaving the predetermined refractive index in the other wavelength of light. The first memberand the second memberare alternately arranged within an incidence plane of the two wavelengths of light, thereby constituting a diffraction grating. The second memberincludes a second resinto dissolve an organic matterhaving optical absorption in a predetermined wavelength range at a molecular level, whereby the refractive index of the second memberis formed.
